7A/400V QRC Power Switch

The Fairchild Power Switch (FPS) KA5Q0740RT 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.
