Feedback Control: This device employs CurrentMode 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 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 17. When VCC reaches 12V, the FSL146MRBN begins switching and the internal highvoltage current source is disabled. The FSL146MRBN continues normal switching operation 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 the PWM comparator (VFB*), as shown in Figure 18. Assuming that the 90μA current source flows only through the internal resistor (3R + R =27kΩ), the cathode voltage of diode D2 is about 2.5V. Since D1 is blocked when the feedback voltage (VFB) exceeds 2.5V, 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 the Current-Mode PWM control. To counter this effect, the leading-edge blanking (LEB) circuit inhibits the PWM comparator for tLEB (300ns) after the SenseFET is turned on. 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 it starts. 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 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. FSL146MRBN — Green-Mode Fairchild Power Switch (FPS™) Functional Description Figure 18. Pulse Width Modulation Circuit © 2012 Fairchild Semiconductor Corporation FSL146MRBN • Rev. 1.0.0 www.fairchildsemi.com 9 B VDS Fault occurs Power on 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 CFB from 2.5V to 7.0V with 2.0µA. A 25 ~ 50ms delay is typical for most applications. This protection is implemented in Auto-Restart Mode. B Fault removed Figure 20. 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 FSL146MRBN has overload protection, it is not enough to protect the FSL146MRBN in that abnormal case; since severe current stress is 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 AOCP 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. VCC 12.0V 7.5V t Normal operation Fault situation Normal operation 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, in normal operation, the overload protection circuit can be triggered during 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, thus 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 © 2012 Fairchild Semiconductor Corporation FSL146MRBN • Rev. 1.0.0 FSL146MRBN — Green-Mode Fairchild Power Switch (FPS™) 4. Protection Circuits: The self-protective functions include: Overload Protection (OLP), Abnormal OverCurrent Protection (AOCP), Output-Short Protection (OSP), Over-Voltage Protection (OVP), and Thermal Shutdown (TSD). All the protections are implemented as Auto Restart Mode. Once the fault condition is detected, switching is terminated and the SenseFET remains off. This causes VCC to fall. When VCC falls to the UnderVoltage 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 AutoRestart 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, the reliability is improved without increasing cost. Figure 21. Abnormal Over-Current Protection www.fairchildsemi.com 10 Figure 22. 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 FSL146MRBN 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. FSL146MRBN — Green-Mode Fairchild Power Switch (FPS™) 5. Soft Burst-Mode Operation: To minimize power dissipation in Standby Mode, the FSL146MRBN 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 VBURL (350mV). At this point, switching stops and the output voltages start to drop at a rate dependent on the 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 switching of the SenseFET, thereby reducing switching loss in Standby Mode. 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 brings high-voltage stress on the drain of the SenseFET when turned off. OSP protects the device from this abnormal condition. It is comprised of detecting VFB and SenseFET turnon 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 22. 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 an external feedback voltage and internal free-running oscillator at every switching instant. RFF effectively scatters the EMI noise around typical switching frequency (67kHz) and can reduce the cost of the input filter used to meet EMI requirements (e.g. EN55022). 4.5 Thermal Shutdown (TSD): The SenseFET and the control IC on a die in one package make it easier for the control IC to detect the over temperature of the SenseFET. If the temperature exceeds ~135C, the thermal shutdown is triggered and stops operation. The FSL146MRBN operates in Auto-Restart Mode until the temperature decreases to around 75C, when normal operation resumes. Figure 24.
