2000 dec 05 3 philips semiconductors preliminary speci?cation greenchip ? ii smps control ic TEA1507 general description the greenchip ? ii is the second generation of green switched mode power supply (smps) controller ics operating directly from the rectified universal mains. a high level of integration leads to a cost effective power supply with a very low number of external components. the special built-in green functions allow the efficiency to be optimum at all power levels. this holds for quasi-resonant operation at high power levels, as well as fixed frequency operation with valley switching at medium power levels. at low power (standby) levels, the system operates at reduced frequency and with valley detection. if burst mode operation is applied, the standby power level can even be reduced to below 1 w. the proprietary high voltage bcd800 process makes direct start-up possible from the rectified mains voltage in an effective and green way. a second low voltage bicmos ic is used for accurate, high speed protection functions and control. highly efficient, reliable supplies can easily be designed using the greenchip ? ii controller. ordering information type number package name description version TEA1507p dip8 plastic dual in-line package; 8 leads (300 mil) sot97-1

2000 dec 05 6 philips semiconductors preliminary speci?cation greenchip ? ii smps control ic TEA1507 current mode control current mode control is used for its good line regulation behaviour. the on-time is controlled by the internally inverted control pin voltage, which is compared with the primary current information. the primary current is sensed across an external resistor. the driver output is latched in the logic, preventing multiple switch-on. the internal control voltage is inversely proportional to the external control pin voltage, with an offset of 1.5 v. this means that a voltage range from 1 to 1.5 v on pin ctrl will result in an internal control voltage range from 0.5 to 0 v (the maximum external control voltage results in a minimum duty cycle). oscillator the maximum fixed frequency of the oscillator is set by an internal current source and capacitor. the maximum frequency is reduced once the control voltage enters the vco control window. then, the maximum frequency changes linearly with the control voltage until the minimum frequency is reached (see figs 5 and 6). valley switching (see fig.7) a new cycle starts when the power switch is switched on. after the on-time (which is determined by the sense voltage and the internal control voltage), the switch is opened and the secondary stroke starts. after the secondary stroke, the drain voltage shows an oscillation with a frequency of approximately where l p is the primary self inductance of the transformer and c d is the capacitance on the drain node. as soon as the oscillator voltage is high again and the secondary stroke has ended, the circuit waits for the lowest drain voltage before starting a new primary stroke. this method is called valley detection. figure 7 shows the drain voltage together with the valley signal, the signal indicating the secondary stroke and the oscillator signal. in an optimum design, the reflected secondary voltage on the primary side will force the drain voltage to zero. thus, zero voltage switching is very possible, preventing large capacitive switching losses , and allowing high frequency operation, which results in small and cost effective inductors. demagnetization the system will be in discontinuous conduction mode all the time. the oscillator will not start a new primary stroke until the secondary stroke has ended. demagnetization features a cycle-by-cycle output short-circuit protection by immediately lowering the frequency (longer off-time), thereby reducing the power level. demagnetization recognition is suppressed during the first t suppr time. this suppression may be necessary in applications where the transformer has a large leakage inductance and at low output voltages/start-up. minimum and maximum on-time the minimum on-time of the smps is determined by the leading edge blanking (leb) time. the ic limits the on-time to 50 m s. when the system desires an on-time longer than 50 m s, a fault condition is assumed (e.g. removed c i ), the ic will stop switching and enter the safe restart mode. 1 2 p l p c d () () ---------------------------------------------------- p 1 2 -- - cv 2 f = ? ?? handbook, halfpage v ctrl 1 v (typ) 0.5 v 1.5 v (typ) mgu233 v sense(max) fig.5 the v sense(max) voltage as function of v ctrl . handbook, halfpage v sense(max) mgu234 f 6 khz 175 khz 50 mv (typ) 75 mv (typ) fig.6 the vco frequency as function of v sense(max)

2000 dec 05 8 philips semiconductors preliminary speci?cation greenchip ? ii smps control ic TEA1507 overvoltage protection (ovp) an ovp mode is implemented in the greenchip ? series. for the TEA1507, this works by sensing the auxiliary voltage via the current flowing into pin dem during the secondary stroke. the auxiliary winding voltage is a well-defined replica of the output voltage. any voltage spikes are averaged by an internal filter. if the output voltage exceeds the ovp trip level, the ovp circuit switches the power mosfet off. next, the controller waits until the uvlo level is reached on pin v cc . this is followed by a safe restart cycle, after which switching starts again. this process is repeated as long as the ovp condition exists. the output voltage at which the ovp function trips, v o(ovp) can be set by the demagnetization resistor, r dem : where n s is the number of secondary turns and n aux is the number of auxiliary turns of the transformer. current i ref is internally trimmed. the value of the demagnetization resistor (r dem ) can be adjusted to the turns ratio of the transformer, thus making an accurate ovp possible. overcurrent protection (ocp) the cycle-by-cycle peak drain current limit circuit uses the external source resistor to measure the current accurately. this allows optimum size determination of the transformer core (cost issue). the circuit is activated after the leading edge blanking time, t leb . the ocp protection circuit limits the sense voltage to an internal level. overpower protection (opp) during the primary stroke, the rectified mains input voltage is measured by sensing the current drawn from pin dem. this current is dependent on the mains voltage, according to the following formula: where: the current information is used to adjust the peak drain current, which is measured via pin i sense . the internal compensation is such that an almost mains independent maximum output power can be realized. the opp curve is given in fig.8. short winding protection after the leading edge blanking time, the short winding protection circuit is also activated. if the sense voltage exceeds the short winding protection voltage v swp , the converter will stop switching. once v cc drops below the uvlo level, capacitor c vcc will be recharged and the supply will restart again. this cycle will be repeated until the short circuit is removed (safe restart mode). the short winding protection will also protect in case of a secondary diode short circuit. overtemperature protection an accurate temperature protection is provided in the circuit. when the junction temperature exceeds the thermal shutdown temperature, the ic will stop switching. when v cc drops to uvlo, capacitor c vcc will be recharged to the v start level. if the temperature is still too high, v cc will drop again to the uvlo level, etc. (safe restart mode). operation recommences when the junction temperature drops 8 degrees typically. v o ovp () n s n aux ----------- i (ovp)(dem) r dem v clamp dem () pos () + () = i dem () v aux r dem -------------- - nv mains r dem -------------------------- ?? n n aux n p ------------ = handbook, halfpage mgu236 0.50 v (typ) 0.3 v (typ) i dem v sense(max) - 24 m a (typ) - 100 m a (typ) fig.8 opp correction curve.
2000 dec 05 9 philips semiconductors preliminary speci?cation greenchip ? ii smps control ic TEA1507 burst mode standby pin ctrl (pin 3) is also used to implement the burst mode standby. in burst mode standby, the power supply enters a special low dissipation state, where it typically consumes less than 1 w of input power (p o < 100 mw), but is still able to supply a microprocessor, for example. figure 12 shows a flyback converter using the burst mode standby function. the system enters burst mode standby when the microprocessor closes switches s2 and s3 on the secondary side. switch s2 connects the high voltage output secondary winding to the low voltage microprocessor capacitor (c m c ), bypassing c o . when the voltage on c m c exceeds the zener voltage, the opto-coupler is activated, sending a large current signal to ctrl. in response to this signal, the ic stops switching and enters a hiccup mode. this burst activation signal should be present for longer than the burst blank period (typically 30 m s): the blanking time prevents false burst triggering due to spikes. figure 11 shows the burst-mode standby signals. the hiccup mode during burst mode standby operation does not differ from the hiccup mode in safe-restart mode during a system fault condition (e.g. ovp or output short circuit). the power is reduced during soft-restart mode. burst mode standby operation continues until the microcontroller opens switches s2 and s3. the system then enters the start-up sequence and begins normal switching behaviour. (for burst mode specification, see figs 11 and 12.) soft start-up (pin i sense ) to prevent transformer rattle during hiccup, the transformer peak current is slowly increased by the soft start function. this can be achieved by inserting a resistor and a capacitor between pin i sense (pin 5) and the sense resistor. an internal current source charges the capacitor to v = i ss r ss , with a maximum of about 0.5 v. the start level and the time constant of the increasing primary current level can be adjusted externally by changing the values of r ss and c ss . the charging current i ss will flow as long as the voltage on pin i sense is below approximately 0.5 v. if the voltage on pin i sense exceeds the 0.5 v, the soft start current source will start limiting the current i ss . at the v cc(start) level, the i ss current source is completely switched off (see fig.9). since the soft start current i ss is subtracted from pin v cc charging current, the r ss value will affect the v cc charging current level by a maximum of 60 m a (typical value). driver the driver circuit to the gate of the power mosfet has a current sourcing capability of typically 125 ma and a current sink capability of typical 540 ma. this permits fast turn-on and turn-off of the power mosfet for efficient operation. a low driver source current has been chosen to limit the d v/ d t at switch-on. this reduces electro magnetic interference (emi) and also limits the current spikes across r sense . i burstmode v th r ctrl ---------------- - i th on () + = i primary(max) v ocp i ss r ss () C r sense ------------------------------------------- - = t r ss c ss = handbook, halfpage c ss r ss i sense r sense i ss v ocp start-up mgu237 pin 5 0.5 v fig.9 soft start-up.
