KA5Q0740RT Fairchild Power Switch FPS • 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 The Fairchild Power Switch FPS product family is specially designed for an off-line SMPS with minimal external components. The Fairchild Power Switch FPS consists of a high voltage power SenseFET and a current mode PWM IC. The integrated PWM controller includes the fixed oscillator, the under voltage lock out, the leading edge blanking, the optimized gate turn-on/turn-off driver, the thermal shut down protection, the over voltage protection, and the temperature compensated precision current sources for loop compensation and fault protection circuitry. Compared to a discrete MOSFET and a controller or a RCC switching converter solutions, a Fairchild Power Switch FPS can reduce the total number of components, design size, and weight, so it will improve efficiency, productivity, and system reliability. It has a basic platform well suited for cost-effective design in a quasi-resonant converter as a C-TV power supply.
