www.fairchildsemi.com KA5Q-SERIES KA5Q0765RT/KA5Q12656RT/KA5Q1265RF/ KA5Q1565RF Fairchild Power Switch(FPS) Features • Quasi Resonant Converter Controller • Internal Burst Mode Controller for Stand-by Mode • Pulse by Pulse Current Limiting • Over Current Latch Protection • Over Voltage Protection (Vsync: Min. 11V) • Internal Thermal Shutdown Function • Under Voltage Lockout • Internal High Voltage Sense FET • Auto-Restart Mode Description 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, and weight and at the same time increase & efficiency, productivity, and system reliability. It has a basic platform well suited for cost-effective design in quasi resonant converter as C-TV power supply. TO-220F-5L TO-3PF-5L Internal Block Diagram 11 1. Drain 2. GND 3. VCC 4. FB 5.
