XCM519 Series
GENERAL DESCRIPTION
ETR2421-003
600mA Synchronous Step-Down DC/DC Converter + Low Voltage Input LDO
The XCM519 series is a multi combination module IC which comprises of a 600mA driver transistor built-in synchronous step-down DC/DC converter and a low voltage input LDO regulator. The device is housed in small USP-12B01 package which is ideally suited for space conscious applications. Battery operated portable products require high efficiency so that a dual DC/DC converter is often used. The XCM519 can replace this dual DC/DC to eliminate one inductor and reduce output noise. The DC/DC converter and the LDO regulator blocks are isolated in the package so that noise interference from the DC/DC to the LDO regulator is minimal. A low output voltage and low On-resistance LDO regulator is added in series to the DC/DC output so that one another low output voltage is created with a high efficiency and low noise. With comparison to the dual DC/DC solution, one inductor can be eliminated which results in parts reduction and board space saving.

OPERATIONAL EXPLANATION
DC/DC BLOCK
The DC/DC block of the XCM519 series consists of a reference voltage source, ramp wave circuit, error amplifier, PWM comparator, phase compensation circuit, output voltage adjustment resistors, P-channel MOSFET driver transistor, N-channel MOSFET switching transistor for the synchronous switch, current limiter circuit, UVLO circuit and others. (See the block diagram above.) The series ICs compare, using the error amplifier, the voltage of the internal voltage reference source with the feedback voltage from the DCOUT pin through split resistors, R1 and R2. Phase compensation is performed on the resulting error amplifier output, to input a signal to the PWM comparator to determine the turn-on time during PWM operation. The PWM comparator compares, in terms of voltage level, the signal from the error amplifier with the ramp wave from the ramp wave circuit, and delivers the resulting output to the buffer driver circuit to cause the Lx pin to output a switching duty cycle. This process is continuously performed to ensure stable output voltage. The current feedback circuit monitors the P-channel MOS driver transistor current for each switching operation, and modulates the error amplifier output signal to provide multiple feedback signals. This enables a stable feedback loop even when a low ESR capacitor such as a ceramic capacitor is used ensuring stable output voltage. The reference voltage source provides the reference voltage to ensure stable output voltage of the DC/DC converter. The ramp wave circuit determines switching frequency. The frequency is fixed internally and can be selected from 1.2MHz or 3.0MHz. Clock pulses generated in this circuit are used to produce ramp waveforms needed for PWM operation, and to synchronize all the internal circuits. The error amplifier is designed to monitor output voltage. The amplifier compares the reference voltage with the feedback voltage divided by the internal split resistors, R1 and R2. When a voltage is lower than the reference voltage is fed back, the output voltage of the error amplifier increases. The gain and frequency characteristics of the error amplifier output are fixed internally to deliver an optimized signal to the mixer.

OPERATIONAL EXPLANATION (Continued)
The current limiter circuit of the XCM519 series monitors the current flowing through the P-channel MOS driver transistor connected to the Lx pin, and features a combination of the current limit mode and the operation suspension mode. When the driver current is greater than a specific level, the current limit function operates to turn off the pulses from the Lx pin at any given timing. When the driver transistor is turned off, the limiter circuit is then released from the current limit detection state. At the next pulse, the driver transistor is turned on. However, the transistor is immediately turned off in the case of an over current state. When the over current state is eliminated, the IC resumes its normal operation. The IC waits for the over current state to end by repeating the steps through . If an over current state continues for a few ms and the above three steps are repeatedly performed, the IC performs the function of latching the OFF state of the driver transistor, and goes into operation suspension mode. Once the IC is in suspension mode, operations can be resumed by either turning the IC off via the CE/MODE pin, or by restoring power to the VIN pin. The suspension mode does not mean a complete shutdown, but a state in which pulse output is suspended; therefore, the internal circuitry remains in operation. The current limit of the XCM519 series can be set at 1050mA at typical. Besides, care must be taken when laying out the PC Board, in order to prevent miss-operation of the current limit mode. Depending on the state of the PC Board, latch time may become longer and latch operation may not work. In order to avoid the effect of noise, the board should be laid out so that input capacitors are placed as close to the IC as possible.

The short-circuit protection circuit monitors the internal R1 and R2 divider voltage from the DCOUT pin. In case where output is accidentally shorted to the Ground and when the FB point voltage decreases less than half of the reference voltage (Vref) and a current more than the ILIM flows to the driver transistor, the short-circuit protection quickly operates to turn off and to latch the driver transistor. In latch state, the operation can be resumed by either turning the IC off and on via the EN1 pin, or by restoring power supply to the VIN1 pin. When sharp load transient happens, a voltage drop at the DCOUT pin is propagated to FB point through CFB, as a result, short circuit protection may operate in the voltage higher than 1/2 VOUT voltage. When the VIN1 pin voltage becomes 1.4V or lower, the P-channel output driver transistor is forced OFF to prevent false pulse output caused by unstable operation of the internal circuitry. When the VIN1 pin voltage becomes 1.8V or higher, switching operation takes place. By releasing the UVLO function, the IC performs the soft start function to initiate output startup operation. The soft start function operates even when the VIN pin voltage falls momentarily below the UVLO operating voltage. The UVLO circuit does not cause a complete shutdown of the IC, but causes pulse output to be suspended; therefore, the internal circuitry remains in operation.

In the PFM control operation, until coil current reaches to a specified level (DLIMIT_PFM), the IC keeps the P-ch MOSFET on. In this case, on-time (tON) that the P-ch MOSFET is kept on can be given by the following formula. tON= L IPFM (VIN1 VDCOUT) IPFM In the PFM control operation, the PFM duty limit (DLIMT_PFM) is set to 200% (TYP.). Therefore, under the condition that the duty increases (e.g. the condition that the step-down ratio is small), it's possible for P-ch MOSFET to be turned off even when coil current doesn't reach to IPFM.

CL High Speed Discharge XCM519xC/ XCM519xD series can quickly discharge the electric charge at the output capacitor (CL) when a low signal to the CE pin which enables a whole IC circuit put into OFF state, is inputted via the N-channel transistor located between the LX pin and the VSS pin. When the IC is disabled, electric charge at the output capacitor (CL) is quickly discharged so that it may avoid application malfunction. Discharge time of the output capacitor (CL) is set by the CL auto-discharge resistance (R) and the output capacitor (CL). By setting time constant of a CL auto-discharge resistance value [R] and an output capacitor value (CL) as ( =C x R), discharge time of the output voltage after discharge via the N channel transistor is calculated by the following formula.

Voltage Regulator BLOCK
The voltage divided by resistors R1 & R2 is compared with the internal reference voltage by the error amplifier. The N-channel MOSFET which is connected to the VROUT pin is then driven by the subsequent output signal. The output voltage at the VROUT pin is controlled & stabilized by a system of negative feedback. VBIAS pin is power supply pin for output voltage control circuit, protection circuit and CE circuit. When output current increase, the VBIAS pin supplies output current also. VIN2 pin is connected to a driver transistor and provides output current. In order to obtain high efficient output current through low on-resistance, please take enough Vgs (=VBIAS - VROUT (T)) of the driver transistor. Output current triggers operation of constant current limiter and fold-back circuit, heat generation triggers operation of thermal shutdown circuit, the driver transistor circuit is forced OFF when VBIAS or VIN2 voltage goes lower than UVLO voltage. Further, the IC's internal circuitry can be shutdown via the EN2 pin's signal.
Figure 1: XC6601B Series
With the XCM519 series, a stable output voltage is achievable even if used with low ESR capacitors, as a phase compensation circuit is built-in. The output capacitor (CL2) should be connected as close to VROUT pin and VSS pin to obtain stable phase compensation. Values required for the phase compensation are as the table below. For a stable power input, please connect an bias capacitor (CBIAS ) of 1.0 F between the VBIAS pin and the VSS pin. Also, please connect an input capacitor (CIN2) of 1.0 F between the VIN2 pin and the VSS pin. In order to ensure the stable phase compensation while avoiding run-out of values, please use the capacitor (CBIAS, CIN2, CL2 ) which does not depend on bias or temperature too much. The table below shows recommended values of CBIAS, CIN, CL.

With the XCM519, the inrush current from VIN2 to VROUT for charging CL at start-up can be reduced and makes the VIN2 stable. The soft-start time is optimized to 240 A (TYP.) at VROUT=1.2V internally. Soft-start time is defined as the VROUT reaches 90% of VROUT (E) from the time when CE H threshold 0.75V is input to the CE pin.

XCM519 series can quickly discharge the electric charge at the output capacitor (CL) when a low signal to the EN2 pin which enables a whole IC circuit put into OFF state, is inputted via the N-channel transistor located between the VROUT pin and the VSS pin. When the IC is disabled, electric charge at the output capacitor (CL) is quickly discharged so that it could avoids malfunction. At that time, CL discharge resistance is depended on a bias voltage. Discharge time of the output capacitor (CL) is set by the CL auto-discharge resistance (R) and the output capacitor (CL). By setting time constant of a CL auto-discharge resistance value [R] and an output capacitor value (CL) as ( =C x R), the output voltage after discharge via the N channel transistor is calculated by the following formulas.
V = VROUT(E)x e -t/ , or =lnVROUT(E) / V V : Output voltage after discharge, VROUT(E) : Output voltage, t: Discharge time, : CL auto-discharge resistance R Output capacitor (CL) value C
The XCM519 series' fold-back circuit operates as an output current limiter and a short protection of the output pin. When the load current reaches the current limit level, the fixed current limiter circuit operates and output voltage drops. When the output pin is shorted to the VSS level, current flows about 50mA.
When the junction temperature of the built-in driver transistor reaches the temperature limit level (150 TYP.), the thermal shutdown circuit operates and the driver transistor will be set to OFF. The IC resumes its operation when the thermal shutdown function is released and the IC's operation is automatically restored because the junction temperature drops to the level of the thermal shutdown release temperature (135 TYP.).
When the VBIAS pin voltage drops below 2.0V (TYP.) or VIN2 pin voltage drops below 0.4V (TYP.), the output driver transistor is forced OFF by UVLO function to prevent false output caused by unstable operation of the internal circuitry. When the VBIAS pin voltage rise at 2.2V (TYP.) or the VIN2 pin voltage rises at 0.4V (TYP.), the UVLO function is released. The driver transistor is turned in the ON state and start to operate voltage regulation.

XCM519 Series
OPERATIONAL EXPLANATION (Continued)
The IC internal circuitry can be shutdown via the signal from the EN2 pin with the XCM519 series. In shutdown mode, output at the VROUT pin will be pulled down to the VSS level via R1 & R2. However, as for the XCM519 series, the CL auto-discharge resistor is connected in parallel to R1 and R2 while the power supply is applied to the VIN2 pin. Therefore, time until the VROUT pin reaches the VSS level becomes short. The EN2 pin of XCM519 has pull-down circuitry so that EN2 input current increase during IC operation. The EN2 pin of XCM519 does not have pull-down circuitry so that logic is not fixed when the CE pin is open. If the EN2 pin voltage is taken from VBIAS pin or VSS pin then logic is fixed and the IC will operate normally. However, supply current may increase as a result of through current in the IC's internal circuitry when medium voltage is input.
NOTE ON USE
1. When the DC/DC converter and the VR are connected as VIN1=VBIAS, VDCOUT=VIN2, the following points should be noted. When the DC/DC load is changed drastically during a light load of the VR, a fluctuation may happen in tenths of mV. This value can be reduced by increasing CL1 load capacitance at the DC/DC in order to reduce a voltage drop during load transient.

It is recommended that both CIN1 and CBIAS are connected to each pin separately. When one capacitor is used instead of the two, this capacitor should be placed in 10 F or more as close as the VIN1 and the PGND (AGND) pins of the DC/DC circuit. Please ensure it by testing on the actual product design. 3. It is recommended that both CL1 and CIN2 are connected to each pin separately. When one capacitor is used instead of the two, this capacitor should be selected in 4.7 F or bigger. Please ensure it by testing on the actual product design. 4. CL2 of the VR is recommended 4.7 A. When larger value is used in CL2, the larger value is also used in CL1 as in proportional. Please be noted that when CL2 capacitance of the VR is getting large, an inrush current increases at VR start-up, DC/DC short circuit protection starts to operate, as a result, the IC may happen to stop.

5. When the input-output voltage differential is small in the DC/DC converter and heavy load condition, a duty cycle is getting large and keeps the 100% duty cycle in a several period cycles. At the time of duty cycle transition to 100% or from 100%, noise may appear on the voltage regulator output. Please evaluate this on the actual design board when the condition is in small input-output voltage differential and heavy load. When the load is changed at the DC/DC converter, ringing may happen in some load conditions of DC/DC and VR at the timing of turn on and turn off. The ringing can be reduced by increasing CIN1 capacitance or placing a resistor over 10k between VIN1 and VBIAS pins. In order to turn off the input voltage, the EN2 pin should be turned off first. If the input voltage is turned off with keeping VR operation, the VROUT voltage goes up instantaneously as a result of the VR bias voltage transient.

8. When the DCOUT pin is connected to the VIN2 pin and the bias voltage (VBIAS) is taken from the other power supply, EN1 and EN2 should be started up 10 s later than VBIAS. If EN1 and EN2 is turned on within 10 s, inrush current like 1A may happen which result in starting the DC/DC short-circuit protection.
9.
It is recommended to test this in the actual product design board.
1. The XCM519 series is designed for use with ceramic output capacitors. If, however, the potential difference is too large between the input voltage and the output voltage, a ceramic capacitor may fail to absorb the resulting high switching energy and oscillation could occur on the output. If the input-output potential difference is large, connect an electrolytic capacitor in parallel to compensate for insufficient capacitance. 2. Spike noise and ripple voltage arise in a switching regulator as with a DC/DC converter. These are greatly influenced by external component selection, such as the coil inductance, capacitance values, and board layout of external components. Once the design has been completed, verification with actual components should be done. 3. As a result of input-output voltage and load conditions, oscillation frequency goes to 1/2, 1/3, and continues, then a ripple may increase. 4. When input-output voltage differential is large and light load conditions, a small duty cycle comes out. After that, 0%duty cycle may continue in several periods. 5. When input-output voltage differential is small and heavy load conditions, a large duty cycle comes out and may continues100% duty cycle in several periods. 6. With the IC, the peak current of the coil is controlled by the current limit circuit. Since the peak current increases when dropout voltage or load current is high, current limit starts operation, and this can lead to instability. When peak current becomes high, please adjust the coil inductance value and fully check the circuit operation. In addition, please calculate the peak current according to the following formula: Ipk = (VIN1-VDCOUT)x OnDuty /(2xLxfOSC) + IOUT L: Coil Inductance Value fOSC: Oscillation Frequency

7. When the peak current which exceeds limit current flows within the specified time, the built-in P-ch driver transistor turns off. During the time until it detects limit current and before the built-in transistor can be turned off, the current for limit current flows; therefore, care must be taken when selecting the rating for the external components such as a coil. 8. Care must be taken when laying out the PC Board, in order to prevent misoperation of the current limit mode. Depending on the state of the PC Board, latch time may become longer and latch operation may not work. In order to avoid the effect of noise, the board should be laid out so that input capacitors are placed as close to the IC as possible. 9. Use of the IC at voltages below the recommended voltage range may lead to instability. 10. This IC should be used within the stated absolute maximum ratings in order to prevent damage to the device. 11. When the IC is used in high temperature, output voltage may increase up to input voltage level at no load because of the leak current of the driver transistor. 12. The current limit is set to 1350mA (MAX.) at typical. However, the current of 1350mA or more may flow. In case that the current limit functions while the DCOUT pin is shorted to the GND pin, when P-ch MOSFET is ON, the potential difference for input voltage will occur at both ends of a coil. For this, the time rate of coil current becomes large. By contrast, when N-ch MOSFET is ON, there is almost no potential difference at both ends of the coil since the DCOUT pin is shorted to the GND pin. Consequently, the time rate of coil current becomes quite small. According to the repetition of this operation, and the delay time of the circuit, coil current will be converged on a certain current value, exceeding the amount of current, which is supposed to be limited originally. Even in this case, however, after the over current state continues for several ms, the circuit will be latched. A coil should be used within the stated absolute maximum rating in order to prevent damage to the device. Current flows into P-ch MOSFET to reach the current limit (ILIM). The current of ILIM or more flows since the delay time of the circuit occurs during from the detection of the current limit to OFF of P-ch MOSFET. Because of no potential difference at both ends of the coil, the time rate of coil current becomes quite small. Lx oscillates very narrow pulses by the current limit for several ms. The circuit is latched, stopping its operation.

In order to stabilize VIN1's voltage level and oscillation frequency, we recommend that a by-pass capacitor (CIN) be connected as close as possible to the VIN1 & VSS pins. High step-down ratio and very light load may lead an intermittent oscillation. During PWM / PFM automatic switching mode, operating may become unstable at transition to continuous mode. Please verify with actual parts.

16. Please note the inductance value of the coil. The IC may enter unstable operation if the combination of ambient temperature, setting voltage, oscillation frequency, and L value are not adequate.

*When a coil less value of 4.7 H is used at fOSC=1.2MHz or when a coil less value of 1.5H is used at fOSC=3.0MHz, peak coil current more easily reach the current limit ILMI. In this case, it may happen that the IC can not provide 600mA output current. 1. Where wiring impedance is high, operations may become unstable due to noise and/or phase lag depending on output current. Please keep the resistance low between VBIAS, VIN2 and VSS wiring in particular. 2. Please wire the bias capacitor (CBIAS), input capacitor (CIN2) and the output capacitor (CL2) as close to the IC as possible. 3. Capacitance values of these capacitors (CBIAS, CIN2, CL2) are decreased by the influences of bias voltage and ambient temperature. Care shall be taken for capacitor selection to ensure stability of phase compensation from the point of ESR influence. 4. In case of the output capacitor more than CL=22 F is used, ringing of input current occurs when rising time. 5. VIN2 and EN2 should be applied at least 10 s after the bias voltage VBIAS reaches the requested voltage. If VIN2 and EN2 are applied within 10 s, inrush current like 1A may occurs.
Instructions of pattern layouts
Please use this IC within the stated absolute maximum ratings. The IC is liable to malfunction should the ratings be exceeded. 2. In order to stabilize VIN1 VIN2 VBIAS DCOUT VROUT voltage level, we recommend that a by-pass capacitor (CIN1 CIN2 CBIAS CL1 CL2) be connected as close as possible to the VIN1 VIN2 VBIAS DCOUT VROUT and GND VSS pins. 3. Please mount each external component as close to the IC as possible. 4. Wire external components as close to the IC as possible and use thick, short connecting traces to reduce the circuit impedance. 5. VSS AGND PGND VSS ground wiring is recommended to get large area. The IC may goes into unstable operation as a result of VSS voltage level fluctuation during the switching. 6. This series' internal driver transistors bring on heat because of the output current (IOUT) and ON resistance of driver transistors. 1.
