飞兆功率开关（ FPS ） Fairchild Power SwitchFPS

Description

The Power SwitchFPS product family is specially designed for an off-line SMPS with minimal external components. The Fairchild Power SwitchFPS 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 RCCswitching converter solution, a Fairchild Power SwitchFPS can reduce total

component count, design size, and weight and at the same time increase & efficiency, productivity, and system reliability.
