KA5M0965Q Fairchild Power Switch SPS • Precision fixed operating frequency 70kHz • Low start-up current typ. 100uA • Pulse by pulse current limiting • Over Load protection • Over current protection • Over voltage protecton Min. 25V • Internal thermal shutdown function • Under voltage lockout • Internal high voltage sense FET • Latch mode The SPS product family is specially designed for an off-line SMPS with minimal external components. The SPS consist of high voltage power SenseFET and current mode PWM IC. Included PWM controller 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, and temperature compensated precision current sources for loopcompensation and fault protection circuitry. Compared to discrete MOSFET and PWM controller or RCC solution, a SPS 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.
