... Fairchild Semiconductor Corporation Description The FSDH565 is specially designed for an off-line SMPS with minimal external components. The FSDH565 is a monolithic high voltage power switching regulator that combine the SenseFET(LDMOS) with voltage mode PWM control block. Included PWM controller features integrated fixed oscillator, ...

... This is the positive supply voltage input. During start up, power is supplied to this input from Pin 1. When Vcc reaches the UVLO upper threshold (8.7V), the start up Internal Switch (Vstr) turns off and power is supplied from auxiliary transformer winding. This pin is designed to directly drive the converter transformer and is capable of switching a maximum of 650V and 1A ...
