Startup: Figure 16 shows the typical startup circuit and transformer auxiliary winding for the FSCM0565R application. Before the FSCM0565R begins switching, it consumes only startup current (typically 25uA) and the current supplied from the DC link supply current consumed by the FPS (Icc), and charges the external capacitor (Ca) that is connected to the Vcc pin. When Vcc reaches start voltage of 12V (VSTART), the FSCM0565R begins switching, and the current consumed by the FSCM0565R increases to 3mA. Then, the FSCM0565R continues its normal switching operation and the power required for this device is supplied from the transformer auxiliary winding, unless Vcc drops below the stop voltage of 8V (VSTOP). To guarantee the stable operation of the control IC, Vcc has under voltage lockout (UVLO) with 4V hysteresis. Figure 17 shows the relation between the current consumed by the FPS (ICC) and the supply voltage (VCC) C DC Rstr Da VC C FSCM 0565R min = ( 2 ⋅ V line min 1 R str – V start ) ⋅ ------------ where Vlinemin is the minimum input voltage, Vstart is the start voltage (12V) and Rstr is the startup resistor. The startup resistor should be chosen so that Isupmin is larger than the maximum startup current (40uA). If not, VCC can not be charged to the start voltage and FPS will fail to start up. 2. Feedback Control: The FSCM0565R employs current mode control, as shown in Figure 18. An opto-coupler (such as the H11A817A) and a 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 KA431 exceeds the internal reference voltage of 2.5V, the H11A817A LED current increases, thus pulling down the feedback voltage and reducing the duty cycle. This event typically happens when the input voltage is increased or the output load is decreased. 2.1 Pulse-by-pulse Current Limit: Because current mode control is employed, the peak current through the SenseFET is determined by the inverting input of the PWM comparator (Vfb*) as shown in Figure 18. When the current through the opto transistor is zero and the current limit pin (#5) is left floating, the feedback current source (IFB) of 0.9mA flows only through the internal resistor (R+2.5R=2.8k). In this case, the cathode voltage of diode D2 and the peak drain current have maximum values of 2.5V and 2.5A, respectively. The pulse-by-pulse current limit can be adjusted using a resistor to GND on the current limit pin (#5). The current limit level using an external resistor (RLIM) is given by AC line (Vline min - V line max ) ISUP I sup IC C Ca R LIM ⋅ 2.5A I LIM = -----------------------------------2.8k Ω + R LIM Figure 16.

Relation Between Operating Supply Current and Vcc Voltage The minimum current supplied through the startup resistor is given by Figure 18. Pulse Width Modulation (PWM) Circuit 2.2 Leading Edge Blanking (LEB): At the instant the internal SenseFET is turned on, there usually exists a high 10 FSCM0565R current spike through the SenseFET, caused by primary-side capacitance and secondary-side rectifier reverse recovery. Excessive voltage across the Rsense resistor can lead to incorrect feedback operation in the current mode PWM control. To counter this effect, the FSCM0565R employs a leading edge blanking (LEB) circuit. This circuit inhibits the PWM comparator for a short time (TLEB) after the SenseFET is turned on. 3. Protection Circuit: The FSCM0565R has several self protective functions such as over load 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 can be improved without increasing cost. Once the fault condition occurs, switching is terminated and the SenseFET remains off. This causes Vcc to fall. When Vcc reaches the UVLO stop voltage of 8V, the current consumed by the FSCM0565R decreases to the startup current (typically 25uA) and the current supplied from the DC link charges the external capacitor (Ca) that is connected to the Vcc pin. When Vcc reaches the start voltage of 12V, the FSCM0565R resumes its 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). determine whether it is a transient situation or an 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 opto-coupler LED, which also reduces the optocoupler transistor current, thus increasing the feedback voltage (Vfb). If Vfb exceeds 2.5V, D1 is blocked and the 5.3uA current source (Idelay) 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 5.3uA (Idelay). In general, a 10 ~ 50 ms delay time is typical for most applications.

Over Load Protection Vcc 12V 8V t Normal Operation Fault Situation Normal Operation Figure 19. Auto Restart Operation 3.1 Over Load 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. However, even when the SMPS is in the normal operation, the over load protection circuit can be activated during the load transition. To avoid this undesired operation, the over load protection circuit is designed to be activated after a specified time to 11 3.2 Over Voltage Protection (OVP): If the secondary side feedback circuit were to malfunction or a solder defect caused an open in the feedback path, the current through the opto-coupler transistor becomes almost zero. Then, Vfb climbs up in a similar manner to the over load situation, forcing the preset maximum current to be supplied to the SMPS until the over load protection is activated. Because more energy than required is provided to the output, the output voltage may exceed the rated voltage before the over load protection is activated, resulting in the breakdown of the devices in the secondary side. To prevent this situation, an over voltage protection (OVP) circuit is employed. In general, Vcc is proportional to the output voltage and the FSCM0565R 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 to be below 19V. 3.3 Thermal Shutdown (TSD): The SenseFET and the FSCM0565R 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 approximately 145°C, the thermal protection is triggered resulting in shutdown of the FPS. 4. Frequency Modulation: EMI reduction can be accomplished by modulating the switching frequency of a switched power supply. Frequency modulation can reduce EMI by spreading the energy over a wider frequency range than the band width measured by the EMI test equipment. The amount of EMI reduction is directly related to the depth of the reference frequency. As can be seen in Figure 21, the frequency changes from 63KHz to 69KHz in 4ms. voltage to rise. Once it passes VBH (500mV), 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.

Frequency Modulation 5. Soft Start: The FSCM0565R has an internal soft start circuit that increases PWM comparator inverting input voltage together with the SenseFET current slowly after it starts up. The typical soft start time is15ms. The pulse width to the power switching device is progressively increased to establish the correct working conditions for transformers, rectifier diodes and capacitors. The voltage on the output capacitors is progressively increased with the intention of smoothly establishing the required output voltage. Preventing transformer saturation and reducing stress on the secondary diode during start up is also helpful. 6. Burst Operation: To minimize power dissipation in standby mode, the FSCM0565R enters into burst mode operation at light load condition. As the load decreases, the feedback voltage decreases. As shown in Figure 22, the device automatically enters into burst mode when the feedback voltage drops below VBL (300mV). At this point switching stops and the output voltages start to drop at a rate dependent on standby current load. This causes the feedback 12 FSCM0565R Typical application circuit Application Output Power LCD Monitor 40W Input Voltage Output Voltage (Max Current) Universal Input 5V (2.0A) (85-265Vac) 12V (2.5A) Features • • • • • • High efficiency (>81% at 85Vac input) Low standby mode power consumption (<1W at 240Vac input and 0.4W load) Low component count Enhanced system reliability through various protection functions Low EMI through frequency modulation Internal soft-start (15ms) Key Design Notes • Resistors R102 and R105 are employed to prevent start-up at low input voltage • The delay time for over load protection is designed to be about 50ms with C106 of 47nF.
