Start-up: In previous generations of Fairchild Power Switches (FPS™), the VCC pin had an external start-up resistor to the DC input voltage line. In this generation, the start-up resistor is replaced by an internal highvoltage current source. At start-up, the internal highvoltage 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 FSDM0x65RE begins switching and the internal high-voltage current source is disabled. The FSDM0x65RE continues normal switching operation and the power is supplied from the auxiliary transformer winding unless VCC goes below the stop voltage of 8V. 2.1 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 18. Assuming that the 0.9mA current source flows only through the internal resistor (2.5R + R = 2.8kΩ), 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, thus clamping VFB*. Therefore, the peak value of the current through the SenseFET is limited. 2.2 Leading Edge Blanking (LEB): At the instant the internal SenseFET is turned on, a high-current spike occurs through the SenseFET, caused by primary-side capacitance and secondary-side rectifier reverse recovery. Excessive voltage across the Rsense resistor would lead to incorrect feedback operation in the current mode PWM control. To counter this effect, the FSDM0x65RE employs a leading-edge blanking (LEB) circuit. This circuit inhibits the PWM comparator for a short time (tLEB) after the SenseFET is turned on.

Pulse-Width-Modulation (PWM) Circuit Figure 17. Internal Start-up Circuit 3. Protection Circuit: The FSDM0x65RE has several self-protective functions, such as overload protection (OLP), over-voltage protection (OVP), and thermal shutdown (TSD). Because these protection circuits are fully integrated into the IC without external components, the reliability is improved without increasing cost. Once a fault condition occurs, switching is terminated and the SenseFET remains off, which causes VCC to fall. When VCC reaches the UVLO stop voltage of 8V, the protection is reset and the internal high-voltage current source charges the VCC capacitor via the Vstr pin. When VCC reaches the UVLO start voltage of 12V, the FSDM0x65RE resumes normal operation. In this manner, the auto-restart can alternately enable and disable the switching of the power SenseFET until the fault condition is eliminated (see Figure 19). 2. Feedback Control: FSDM0x65RE employs currentmode control, as shown in Figure 18. An opto-coupler (such as the H11A817A) 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, plus an offset voltage, 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 optocoupler LED current increases, pulling down the feedback voltage and reducing the duty cycle. This event typically occurs when the input voltage is increased or the output load is decreased. © 2006 Fairchild Semiconductor Corporation FSDM0465RE, FSDM0565RE, FSDM07652RE Rev. 1.0.2 www.fairchildsemi.com 12 FSDM0465RE, FSDM0565RE, FSDM07652RE — Green Mode Fairchild Power Switch (FPS™) VDS Power on Fault occurs Fault removed VFB FSDM0565RE Rev: 00 Overload protection 6.0V 2.5V VCC T12= CFB*(6.0-2.5)/Idelay 12V 8V T1 T2 t t Normal operation Fault situation Normal operation Figure 20. Overload Protection FSDM0565RE Rev: 00 Figure 19. Auto Restart Operation 3.1 Overload Protection (OLP): Overload is defined as the load current exceeding a pre-set level due to an unexpected event. In this situation, the protection circuit should be activated to protect the SMPS. Even when the SMPS is in normal operation, the overload protection circuit can be activated during the load transition. To avoid this undesired operation, the overload protection circuit is designed to be activated 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 beyond this maximum power, the output voltage (VO) decreases below the set voltage. This reduces the current through the optocoupler 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 3.5µA current source starts to charge CB slowly up to VCC. In this condition, VFB continues increasing until it reaches 6V, when the switching operation is terminated, as shown in Figure 20. The delay time for shutdown is the time required to charge CB from 2.5V to 6.0V with 3.5µA. A 10 ~ 50ms delay time is typical for most applications. 3.2 Over-Voltage Protection (OVP): If the secondary side feedback circuit were to malfunction or a solder defect caused an opening in the feedback path, the current through the opto-coupler transistor becomes almost zero. In this event, VFB climbs in a similar manner to the overload situation, forcing the preset maximum current to be supplied to the SMPS until the overload protection is activated. Because more energy than required is provided to the output, the output voltage may exceed the rated voltage before the overload protection is activated, resulting in the breakdown of the devices in the secondary side. To prevent this situation, an overvoltage protection (OVP) circuit is employed. In general, VCC is proportional to the output voltage and the FSDM0x65RE uses VCC instead of directly monitoring the output voltage. If VCC exceeds 19V, an OVP circuit is activated, resulting in the termination of the switching operation. To avoid undesired activation of OVP during normal operation, VCC should be designed below 19V. 3.3 Thermal Shutdown (TSD): The SenseFET and the control IC are built in one package. This makes it easy for the control IC to detect the heat generation from the SenseFET. When the temperature exceeds ~150°C, the thermal shutdown is activated. 4. Soft-Start: The FSDM0x65RE has an internal softstart circuit that increases PWM comparator inverting input voltage, together with the SenseFET current, slowly after it starts up. The typical soft-start time is 10ms. 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 with the intention of smoothly establishing the required output voltage. It also helps prevent transformer saturation and reduces the stress on the secondary diode during start-up. © 2006 Fairchild Semiconductor Corporation FSDM0465RE, FSDM0565RE, FSDM07652RE Rev. 1.0.2 www.fairchildsemi.com 13 FSDM0465RE, FSDM0565RE, FSDM07652RE — Green Mode Fairchild Power Switch (FPS™) 5. Burst Operation: To minimize power dissipation in standby mode, the FSDM0x65RE enters burst-mode operation. As the load decreases, the feedback voltage decreases. As shown in Figure 21, the device automatically enters burst mode when the feedback voltage drops below VBURL(500mV). 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 (700mV), switching resumes. The feedback voltage then falls and the process repeats. Burst-mode operation alternately enables and disables switching of the power SenseFET, thereby reducing switching loss in standby mode.
