Offline Regulators | KA5M0280R

The ON Semiconductor Power Switch (FPS) product family is specially designed for an off-line SMPS with minimal external components. The ON Semiconductor Power Switch (FPS) consist of high voltage power SenseFET and current mode PWM IC. Included 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, and temperature compensated precision current sources for loop compensation and fault protection circuitry. Compared to discrete MOSFET and controller or R_CC switching converter solution, a ON Semiconductor Power Switch (FPS) can reduce total component count, design size, weight and at the same time increase efficiency, productivity, and system reliability. It has a basic platform well suited for cost-effective design in either a flyback converter or a forward converter.
