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
