Feedback Control: This device employs CurrentMode control, as shown in Figure 20. 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 RSENSE resistor makes it possible to control the switching duty cycle. 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. 1. Startup: At startup, an internal high-voltage current source supplies the internal bias and charges the external capacitor (CVCC) connected to the VCC pin, as illustrated in Figure 19. When VCC reaches 12V, the FSL156MRIN begins switching and the internal highvoltage current source is disabled. Normal switching operation continues and the power is supplied from the auxiliary transformer winding unless VCC goes below the stop voltage of 7.5V. 3.1 Pulse-by-Pulse Current Limit: Because CurrentMode control is employed, the peak current through the SenseFET is limited by the inverting input of PWM comparator (VFB*), as shown in Figure 20. Assuming that the 90μA current source flows only through the internal resistor (3R + R =25kΩ), the cathode voltage of diode D2 is about 2.8V. Since D1 is blocked when the feedback voltage (VFB) exceeds 2.8V, the maximum voltage of the cathode of D2 is clamped at this voltage. Therefore, the 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 RSENSE resistor leads to incorrect feedback operation in Current-Mode PWM control. To counter this effect, the LEB circuit inhibits the PWM comparator for tLEB (300ns) after the SenseFET is turned on. Figure 19. 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 voltage. This helps prevent transformer saturation and reduces stress on the secondary diode during startup. FSL156MRIN — Green-Mode Fairchild Power Switch (FPS™) Functional Description Figure 20. Pulse Width Modulation Circuit © 2012 Fairchild Semiconductor Corporation FSL156MRIN • Rev. 1.0.0 www.fairchildsemi.com 10 B increasing until it reaches 7.0V, when the switching operation is terminated, as shown in Figure 22. The delay for shutdown is the time required to charge CFB from 2.5V to 7.0V with 2.0µA. A 25 ~ 50ms delay is typical for most applications. This protection is implemented as auto-restart. B Figure 22. Overload Protection 4.2 Abnormal Over-Current 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 FSL156MRIN has overload protection, it is not enough to protect the FSL156MRIN 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 23. 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 AOCP level. If the sensingresistor 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. 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 overload protection circuit is designed to trigger only after a specified time to determine whether it is a transient situation or a true overload situation. Because of the pulse-by-pulse current-limit capability, the maximum peak current through the SenseFET is limited and, therefore, the maximum input power is restricted with a given input voltage. If the output consumes more than this maximum power, the output voltage (VOUT) 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 (VFB). If VFB exceeds 2.5V, D1 is blocked and the 2.0µA current source starts to charge CFB slowly up. In this condition, VFB continues © 2012 Fairchild Semiconductor Corporation FSL156MRIN • Rev. 1.0.0 FSL156MRIN — Green-Mode Fairchild Power Switch (FPS™) 4. Protection Circuits: The FSL156MRIN 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 VCC to fall. When VCC falls to the Under-Voltage Lockout (UVLO) stop voltage of 7.5V, the protection is reset and the startup circuit charges the VCC capacitor. When VCC reaches the start voltage of 12.0V, normal operation resumes. If the fault condition is not removed, the SenseFET remains off and VCC drops to stop voltage again. In this manner, the auto-restart can alternately enable and disable the switching of the power SenseFET until the fault condition is eliminated. Because these protection circuits are fully integrated into the IC without external components, reliability is improved without increasing cost. Figure 23. Abnormal Over-Current Protection www.fairchildsemi.com 11 Figure 25. Line Over-Voltage Protection 5. Soft Burst Mode: To minimize power dissipation in Standby Mode, the FSL156MRIN enters Burst-Mode operation. As the load decreases, the feedback voltage decreases. As shown in Figure 22, the device automatically enters Burst Mode when the feedback voltage drops below VBURL (350mV). At this point, switching stops and the output voltages start to drop at a rate dependent on standby current load. This causes the feedback voltage to rise. Once it passes VBURH (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 24. Output-Short Protection 4.4 Over-Voltage Protection (OVP): If the secondary-side feedback circuit malfunctions or a solder defect causes an opening in the feedback path, the current through the opto-coupler transistor becomes almost zero. Then VFB climbs up in a similar manner to the overload situation, 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 VCC is proportional to the output voltage and the FSL156MRIN uses VCC instead of directly monitoring the output voltage. If VCC exceeds 24.5V, an OVP circuit is triggered, resulting in the termination of the switching operation. To avoid undesired activation of OVP during normal operation, VCC should be designed to be below 24.5V. FSL156MRIN — Green-Mode Fairchild Power Switch (FPS™) 4.6 Line Over-Voltage Protection (LOVP): If the line input voltage is increased to an unwanted level, high line input voltage creates high-voltage stress on the entire system. To protect from this abnormal condition, LOVP is included. It is comprised of detecting VIN using divided resistors. When VIN is higher than 1.95V, this condition is recognized as an abnormal error and PWM switching shuts down until VIN decreases to around 1.89V (60mV hysteresis). 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 turnon time. Such a steep current creates 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 VFB and SenseFET turn-on time. When the VFB is higher than 2.0V and the SenseFET turn-on time is lower than 1.0μs, this condition is recognized as an abnormal error and PWM switching shuts down until VCC reaches VSTART again. An abnormal condition output short is shown in Figure 24. 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 temperature of the SenseFET. If the temperature exceeds ~135C, the thermal shutdown is triggered and stops operation. The FSL156MRIN operates in Auto-Restart Mode until the temperature decreases to around 75C, when normal operation resumes. Figure 26.

Random Frequency Fluctuation © 2012 Fairchild Semiconductor Corporation FSL156MRIN • Rev. 1.0.0 FSL156MRIN — Green-Mode Fairchild Power Switch (FPS™) 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 an internal free-running oscillator at every switching instant. RFF effectively scatters EMI noise around typical switching frequency (67kHz) and can reduce the cost of the input filter included to meet the EMI requirements (e.g. EN55022). www.fairchildsemi.com 13 FSL156MRIN — Green-Mode Fairchild Power Switch (FPS™) Package Dimensions 9.83 9.00 6.67 6.096 8.255 7.61 3.683 3.20 5.08 MAX 7.62 0.33 MIN 3.60 3.00 (0.56) 2.54 0.56 0.355 0.356 0.20 9.957 7.87 1.65 1.27 7.62 NOTES: UNLESS OTHERWISE SPECIFIED A) THIS PACKAGE CONFORMS TO JEDEC MS-001 VARIATION BA B) ALL DIMENSIONS ARE IN MILLIMETERS.
