Description

The Fairchild Power Switch(FPS) product family KA1M0765RC is specially designed for an off line SMPS with minimal external components. The Fairchild Power Switch(FPS) KA1M0765RC consist of high voltage power SenseFET and current mode PWM controller IC. PWM controller KA1M0765RC features integrated fixed frequency oscillator, under voltage lock out, leading edge blanking, optimized gate turn-on/turn-off driver, thermal shutdown protection, over voltage protection, temperature compensated precision current sources for loop compensation and fault protection circuit. compared to discrete MOSFET and PWM controller or RCC 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. KA1M0765RC has a basic platform well suited for cost effective design in either a flyback converter or a forward converter.
