Description

The Fairchild Power Switch(FPS) KA1H0365R product family is specially designed for an off line SMPS with minimal external
components. The Fairchild Power Switch(FPS) KA1H0365R consist of high voltage power SenseFET and current mode PWM
controller IC. PWM controller KA1H0365R 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. The KA1H0365R has a basic platform well suited for cost effective design in either a  flyback converter or a forward converter.
