.. .fairchildsemi. KA5M0965Q Fairchild Power Switch(SPS) Features - - - - - - - - - - Precision fixed operating frequency (70k Hz) Low start-up current(typ. 100u A) 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 Description The SPS product family is specially designed for an off-line SMPS with minimal external ponents. The SPS consist of high voltage power Sense FET 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 pensated precision current sources for looppensation and fault protection circuitry. pared to discrete MOSFET and PWM controller or RCC solution, a SPS can reduce total ponent 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. TO-3P-5L 1. DRAIN 2. GND 3. VCC 4. FB 5.
