KA1L0880B/KA1M0880B Fairchild Power Switch FPS • Precision fixed operating frequency • KA1L0880B 50KHz ,KA1M0880B 67KHz • Pulse by pulse over current limiting • Over load protection • Over voltage protection Min. 23V • Internal thermal shutdown function • Under voltage lockout • Internal high voltage sense FET • Latch up mode • Soft start The Fairchild Power Switch FPS product family is specially designed for an off-line SMPS with minimal external components. The Fairchild Power Switch FPS consist of high voltage power SenseFET and current mode PWM controller IC. 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, temperature compensated precision current sources for loop compensation and fault protection circuit. compared to discrete MOSFET and controller or RCC switching converter solution, a Fairchild 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.
