Description

The Fairchild Power Switch(FPS) product family KA1M0880B is specially designed for an off-line SMPS with minimal external
components. The Fairchild Power Switch(FPS) KA1M0880B consist of high voltage power SenseFET and current mode PWM controller IC. PWM controller KA1M0880B 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. KA1M0880B has a basic platform well suited for cost effective design in either a flyback converter or a forward converter.
