Fairchild Power Switch(FPS)

The Fairchild Power Switch(FPS) product family is specially designed for an off-line SMPS with minimal external components. The Fairchild Power Switch(FPS) consists of a high voltage power SenseFET and a current mode PWM IC. Included PWM Controller integrates the fixed frequency Oscillator the under voltage lock-out, the leading edge blanking, the optimized Gate turn-on/turn-off driver, the thermal shutdown protection, the over voltage protection, and the temperature compensated precision current sources for the loop compensation and the fault protection circuitry. Compared to a Discrete MOSFET and a PWM Controller or an RCCsolution, a Fairchild Power Switch(FPS) CAN reduce the total component count, design size and weight and at the same time increase efficiency, productivity, and system reliability. It has a basic platform well suited for the cost effective design in either a flyback converter or a forward converter By Fairchild Semiconductor
