Product Summary

Description:The Fairchild Power Switch(FPS) product family is specially designed for an off-line SMPS with minimal external  components. The Fairchild Power Switch(FPS) consist of
high voltage power SenseFET and current mode PWM controller IC. PWM controller features integrated fixed  oscillator, under voltage lock out, leading edge blanking,
optimized gate turn-on/turn-off driver, thermal shut down protection, over voltage protection, temperature compensated
precision current sources for loop compensation and fault protection circuit. compared to discrete MOSFET and  controller or RCC switching converter solution, a Fairchild
Power Switch(FPS) can reduce total component count,design size, weight and at the same time increase &  efficiency, productivity, and system reliability. It has a basic
platform well suited for cost effective design in either a  flyback converter or a forward converter
