? 2011 fairchild semiconductor corporation www.fairchildsemi.com FSD156MRBN ? rev. 1.0.0 9 FSD156MRBN ? green-mode fairchild power switch (fps?) functional description 1. startup: at startup, an internal high-voltage current source supplies the internal bias and charges the external capacitor (c vcc ) connected to the v cc pin, as illustrated in figure 17. when v cc reaches 12v, the FSD156MRBN begins switching and the internal high- voltage current source is disabled. normal switching operation continues and the power is supplied from the auxiliary transformer winding unless v cc goes below the stop voltage of 7.5v. figure 17. startup block 2. soft-start : the internal soft-start circuit increases pwm comparator inverting input voltage, together with the sensefet current, slowly after startup. the typical soft-start time is 15ms. the pulse width to the power switching device is progressively increased to establish the correct working conditions for the transformers, inductors, and capacitors. the voltage on the output capacitors is progressively increased to smoothly establish the required output vo ltage. this helps prevent transformer saturation and reduces stress on the secondary diode during startup. 3. feedback control : this device employs current- mode control, as shown in figure 18. an opto-coupler (such as the fod817) and shunt regulator (such as the ka431) are typically used to implement the feedback network. comparing the feedback voltage with the voltage across the r sense resistor makes it possible to control the switching duty cy cle. when the reference pin voltage of the shunt regulator exceeds the internal reference voltage of 2.5v, the opto-coupler led current increases, pulling down the feedback voltage and reducing drain current. this typically occurs when the input voltage is increased or the output load is decreased. 3.1 pulse-by-pulse current limit : because current- mode control is employed, the peak current through the sensefet is limited by the inverting input of pwm comparator (v fb *), as shown in figure 18. assuming that the 90 a current source flows only through the internal resistor (3r + r =25k ? ), the cathode voltage of diode d2 is about 2.8v. since d1 is blocked when the feedback voltage (v fb ) exceeds 2.8v, the maximum voltage of the cat hode of d2 is clamped at this voltage. therefore, t he peak value of the current through the sensefet is limited. 3.2 leading-edge blanking (leb) : at the instant the internal sensefet is turned on, a high-current spike usually occurs through the sensefet, caused by primary-side capacitance and secondary-side rectifier reverse recovery. excessive voltage across the r sense resistor leads to incorrect feedback operation in the current-mode pwm control. to counter this effect, the leading-edge blanking (leb) circuit inhibits the pwm comparator for t leb (300ns) after the sensefet is turned on. figure 18. pulse width modulation circuit
? 2011 fairchild semiconductor corporation www.fairchildsemi.com FSD156MRBN ? rev. 1.0.0 10 FSD156MRBN ? green-mode fairchild power switch (fps?) 4. protection circuits : the FSD156MRBN has several self-protective functions, such as overload protection (olp), abnormal over-current protection (aocp), output-short protection (osp), over-voltage protection (ovp), and thermal shutdown (tsd). all the protections are implemented as auto-restart. once the fault condition is detected, switching is terminated and the sensefet remains off. this causes v cc to fall. when v b cc b falls to the under-voltage lockout (uvlo) stop voltage of 7.5v, the pr otection is reset and the startup circuit charges the v cc capacitor. when v cc reaches the start voltage of 12.0v, the FSD156MRBN resumes normal operation. if the fault condition is not removed, the sensefet remains off and v cc drops to stop voltage again. in this manner, the auto-restart can alternately enable and disabl e the switching of the power sensefet until the faul t condition is eliminated. because these protection circ uits are fully integrated into the ic without external components, reliability is improved without increasing cost. figure 19. auto-restart protection waveforms 4.1 overload protection (olp) : overload is defined as the load current exceeding its normal level due to an unexpected abnormal event. in this situation, the protection circuit should trigger to protect the smps. however, even when the smps is in normal operation, the overload protection circuit can be triggered during the load transition. to avoid this undesired operation, the over load protection circuit is designed to trigger only after a specified time to determine whether it is a tr ansient situation or a true overload situation. because of the pulse-by-pulse current limit capability, the maximum peak current through the sensefet is li mited and, t herefore, the maximum input power is restricted with a given input voltage. if the output consumes more than this maximum power, the output voltage (v out ) decreases below the set voltage. this reduces the current through the opto-coupler led, which also reduces the opto-coupler transistor current, increasing the feedback voltage (v fb ). if v fb exceeds 2.5v, d1 is blocked and the 2.0a current source starts to charge c fb slowly up . in this condition, v fb continues increasing until it reaches 7.0v, when the switching operation is terminated, as shown in figure 20. the delay for shutdown is the time required to charge c fb from 2.5v to 7.0v with 2.0a. a 25 ~ 50ms delay is typical for most applications. this protection is implemented in auto-restart mode. figure 20. overload protection 4.2 abnormal over-curre nt protection (aocp) : when the secondary rectifier diodes or the transformer pins are shorted, a steep current with extremely high di/dt can flow through the sensefet during the minimum turn-on time. even though the FSD156MRBN has overload protection, it is not enough to protect the FSD156MRBN in that abnormal case; due to the severe current stress imposed on the sensefet until olp is triggered. the internal aocp circuit is shown in figure 21. when the gate turn-on signal is applied to the power sensefet, the aocp block is enabled and monitors the current through the sensing resistor. the voltage across the resistor is compared with a preset ao cp level. if the sensing resistor voltage is greater than the aocp level, the set signal is applied to the s - r latch, resulting in the shutdown of the smps. figure 21. abnormal over-current protection
? 2011 fairchild semiconductor corporation www.fairchildsemi.com FSD156MRBN ? rev. 1.0.0 11 FSD156MRBN ? green-mode fairchild power switch (fps?) 4.3. output-short protection (osp) : if the output is shorted, steep current with extremely high di/dt can flow through the sensefet during the minimum turn- on time. such a steep current brings high-voltage stress on the drain of the sensefet when turned off. to protect the device from this abnormal condition, osp is included. it is comprised of detecting v fb and sensefet turn-on time. when the v fb is higher than 2.0v and the sensefet turn-on time is lower than 1.0 s, this condition is recognized as an abnormal error and pwm switching shuts down until v cc reaches v start again. an abnormal condition output short is shown in figure 22. figure 22. output-short protection 4.4 over-voltage protection (ovp): if the secondary-side feedback circuit malfunctions or a solder defect causes an open ing in the feedback path, the current through the opto-coupler transistor becomes almost zero. then v fb climbs up in a similar manner to the overload sit uation, forcing the preset maximum current to be supplied to the smps until the overload protection is triggered. because more energy than required is provided to the output, the output voltage may exceed the rated voltage before the overload protection is triggered, resulting in the breakdown of the devices in the secondary side. to prevent this situation, an ovp circuit is employed. in general, the v cc is proportional to the output voltage and the FSD156MRBN uses v cc instead of directly monitoring the output voltage. if v cc exceeds 24.5v, an ovp circuit is triggered, resulting in the termination of the switching operati on. to avoid undesired activation of ovp during normal operation, v cc should be designed to be below 24.5v. 4.5 thermal shutdown (tsd) : the sensefet and the control ic on a die in one package makes it easier for the control ic to detect the over temperature of the sensefet. if the temperature exceeds ~135 ? c, the thermal shutdown is tr iggered and stops operation. the FSD156MRBN operates in auto-restart mode until the temperature decreases to around 75 ? c, when normal operation resumes. 5. soft burst-mode operation : to minimize power dissipation in standby mode, the FSD156MRBN enters burst-mode operation. as the load decreases, the feedback voltage decreases. as shown in figure 23, the device automatically enters burst mode when the feedback voltage drops below v burl (350mv). at this point, switching stops and t he output voltages start to drop at a rate dependent on standby current load. this causes the feedback voltage to rise. once it passes v burh (500mv), switching resumes. the feedback voltage then falls and the process repeats. burst mode alternately enables and disables sensefet switching, reducing switching loss in standby mode. figure 23. figure 23. burst-mode operation 6. random frequency fluctuation (rff) : fluctuating switching frequency of an smps can reduce emi by spreading the energy over a wide frequency range. the amount of emi reduction is directly related to the switching frequency variation, which is limited internally. the switching frequency is determined randomly by external feedback voltage and internal free-running oscillator at every switch ing instant. rff effectively scatters emi noise around typical switching frequency (67khz) and can reduce the co st of the input filter included to meet the emi requirements (e.g. en55022). figure 24. random frequency fluctuation
