... I 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 : FSCM0565R employs current mode control, as shown in Figure 6. An opto-coupler (such as the H11A817A) and shunt regulator (such as the KA431) are typically used to implement the feedback network ...

... DC link charges the external capacitor (C ) that is connected to the Vcc pin. When Vcc a reaches the start voltage of 12V, FSCM0565R resumes its normal operation. In this manner, the auto-restart can alternately enable and disable the switching of the power Sense FET until the fault condition is eliminated (see Figure 7) ...

... Figure 9. Frequency Modulation 5. Soft Start : The FSCM0565R has an internal soft start circuit that increases PWM comparator inverting input voltage together with the Sense FET current slowly after it starts up. The typical soft start time is 15msec, The pulse width to the power switching device is progressively increased to establish the correct working conditions for transformers, rectifier diodes and capacitors ...
