www.fairchildsemi.com KA1M0565R/KA1H0565R Fairchild Power Switch(FPS) Features Description · Precision fixed operating frequency The Fairchild Power Switch(FPS) product family is specially · KA1M0565R (67KHz),KA1H0565R (100KHz) designed for an off-line SMPS with minimal external · Pulse by pulse over current limiting components. The Fairchild Power Switch(FPS) consist of · Over load protection high voltage power SenseFET and current mode PWM · Over voltage protection (Min. 23V) controller IC. PWM controller features integrated fixed · Internal thermal shutdown function oscillator, under voltage lock out, leading edge blanking, · Under voltage lockout optimized gate turn-on/turn-off driver, thermal shut down · Internal high voltage sense FET protection, over voltage protection, temperature compensated · Auto restar t precision current sources for loop compensation and faultprotection circuit. compared to discrete MOSFET and controller or RCC switching converter solution, a FairchildPower Switch(FPS) can reduce total component count,design size, weight and at the same time increase & efficiency, productivity, and system reliability. It has a basicplatform well suited for cost effective design in either a flyback converter or a forward converter. TO-220F-4L 1 1. GND 2. DRAIN 3. VCC 4.
