XC6220 Series
1A LDO Voltage Regulator with "GreenOperation"
ETR0341-007
GreenOperation-Compatible
GENERAL DESCRIPTION
The XC6220 series is a highly accurate, low noise, high speed, low dropout, and large current CMOS voltage regulator with GreenOperation function. The series consists of a voltage reference, an error amplifier, a current limiter, an inrush current prevention circuit and a phase compensation circuit plus a driver transistor. With a 0.2 on-resistance driver transistor integrated and with output currents up to 1A, the ultra low dropout voltage performance greatly extends battery life as does the GreenOperation function which can switch between high speed and power save modes automatically. Low ESR ceramic capacitors can be used for the output stabilization capacitor (CL). Output voltage is selectable in 0.05V increments within the range of 0.8V~5.0V, using laser trimming technologies. An over current protection circuit and a thermal shutdown circuit are built in. The over current protection circuit will operate when the output current reaches its limit current. The thermal shutdown circuit will operate when the junction temperature reaches its limit temperature. The inrush protection circuit works by controlling the inrush current which is charged to CL when the IC starts up. In this way, any fluctuations to VIN caused by inrush current during system start up can be minimized. The CE function enables the output to be turned off and the IC becomes a stand-by mode resulting in greatly reduced power consumption.

The dissipation pad for the USP-6C package should be solder-plated in recommended mount pattern and metal masking so as to enhance mounting strength and heat release. If the pad needs to be connected to other pins, it should be connected to the VSS (No. 4)

The output voltage when "VOUT (T)+1.0V" is provided at the VIN pin while maintaining a certain IOUT value. *3: VOUT (T): Nominal output voltage (*6) (*5) *4: Vdif={VIN1 - VOUT1 } *5: VOUT1=A voltage equal to 98% of the VOUT(T) when an amply stabilized IOUT {VOUT(T)+1.0V} is input in the HS mode. *6: VIN1=The input voltage when VOUT1 appears as input voltage is gradually decreased. *7: For the XC6220B/D series only. The XC6220A/C series (semi-custom) discharges by resistors R1 and R2 only as shown in the block diagrams. *8: For the XC6220A/C series, output voltage rises when the IC is in the high temperature stand-by mode.

The voltage divided by resistors R1 & R2 is compared with the internal reference voltage by the error amplifier. The P-channel MOSFET which is connected to the VOUT pin is then driven by the subsequent output signal. The output voltage at the VOUT pin is controlled & stabilized by a system of negative feedback. The current limit circuit and short protect circuit operate in relation to the level of output current. The GO function monitors the output current and switches the IC between two operating modes according to the level of output current. Further, the IC's internal circuitry can be shutdown via the CE pin's signal.
XC6220x 301
The XC6220 series always operates in a green operation (GO) mode. The GO mode enables the IC to switch automatically between the high speed (HS) mode or the power save (PS) mode according to the level of output current. The switching point of the HS mode and the PS mode is fixed inside the IC. When the output current becomes IGOR=1.0mA (MIN.) or below, the mode changes automatically to the PS mode after a delay time of hundreds of microseconds. Supply current in light load is greatly reduced. Also when the output current becomes IGO 10mA (MAX.) or more, the mode changes automatically to the HS mode and the IC returns to high speed operation.

The XC6220 series has a built-in phase compensation circuit which means that a stable output voltage is achieved even if the IC is used with low ESR capacitors. In order to ensure stable phase compensation it is recommended that a CL capacitor is connected as close as possible to the VOUT pin and VSS pin. For a stable power supply, please connect an input capacitor (CIN) between the VIN pin and the VSS pin. Values required for the phase compensation are shown in the chart below. If a loss of the capacitance happens, the stable phase compensation may not be obtained. Please ensure to use a capacitor which does not depend on bias or temperature too much.

The XC6220 series includes a fold-back circuit, which aids the operation of the current limiter and circuit protection. When the load current reaches the current limit level, the fold-back circuit operates and output voltage drops. As a result of this drop in output voltage, output current also decreases. When the output pin is shorted, a current of about 180mA flows.
The IC's internal circuitry can be shutdown via the signal from the CE pin with the XC6220 series. With the XC6220B/D series, output at the VOUT pin will be pulled down to the VSS level. However, with XC6220A/B series, the CL auto-discharge resistor is connected in parallel to R1 and R2 while the power supply is applied to the VIN pin. Therefore, the time until the VOUT pin reaches the VSS level is shortened. The output voltage becomes unstable, when the CE pin is open. If this IC is used with the correct output voltage for the CE pin, the logic is fixed and the IC will operate normally. However, with the XC6220C/D series, supply current may increase as a result of through current in the IC's internal circuitry when medium voltage is input.

OPERATIONAL EXPLANATION (Continued)
The XC6220B/D series can quickly discharge the electric charge at the output capacitor (CL), when a low signal to the CE pin, which enables the whole IC circuit put into an OFF state, is inputted to the CE pin via the N-channel transistor located between the VOUT pin and the VSS pin (cf. BLOCK DIAGRAM). The CL auto-discharge resistance value is fixed to 460 (VIN=6.0V, VOUT=5.0V at TYP.). The discharge time of the output capacitor (CL) is set by the CL auto-discharge resistance (RDCHG) and the output capacitor (CL). By setting a time constant of the CL auto-discharge resistance value [RDCHG] and an output capacitor value (CL) as (=C x RDCHG), the output voltage after discharge via the N channel transistor is calculated by the following formulas. V = VOUT x e -t/, or =ln VOUT(E) / V
where V : Output voltage after discharge VOUT(E) : Output voltage t: Discharge time : CL auto-discharge resistance RDCHGxOutput capacitor (CL) value C)
For the XC6220A/C series, output voltage may rises when in the high stand-by mode. Please note that in that case, the typical characteristics may worse. When the XC6220A/C series is used, please be noted the characteristics shown below.

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 turned 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 voltage. The XC6220 series includes an inrush current protection circuit. The inrush current protection circuit suppresses inrush current charged to CL when the IC starts up to 700 mA (MAX.) for approximately 1 ms. * Please note that the device can not provide the output current beyond 700 mA for a period of approximately 1 ms after the CE pin goes high.
NOTES ON USE
1. Please use this IC within the stated absolute maximum ratings. The IC is liable to malfunction should the ratings be exceeded. 2. Where wiring impedance is high, operations may become unstable due to noise and/or phase lag depending on output current. Please strengthen VIN and VSS wiring in particular. 3. Please wire the input capacitor (CIN) and the output capacitor (CL) as close to the IC as possible.
