Description

The Fairchild Power Switch(FPS) product family KA5L0365R is specially designed for an off-line SMPS with minimal external components. The Fairchild Power Switch(FPS) KA5L0365R 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 oran 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. KA5L0365R has a basic platform well suited for the cost effective design in either a flyback converter or a forward converter.
