    • 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
    • Primary Side Regulation

    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) 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.
