The Fairchild Power Switch(FPS) product family is speciallydesigned for an off-line SMPS with minimal externalcomponents. The Fairchild Power Switch(FPS) consist of highvoltage power SenseFET and current mode PWM controller IC.PWM controller features integrated fixed oscillator, undervoltage lock out, leading edge blanking, optimized gate turn-on/turn-off driver, thermal shut down protection, over voltageprotection, temperature compensated precision current sourcesfor loop compensation and fault protection circuit. compared todiscrete MOSFET and controller or RCC switching convertersolution, a Fairchild Power Switch(FPS) can reduce totalcomponent count, design size, and weight and at the same timeincrease & efficiency, productivity, and system reliability. It hasa basic platform well suited for cost-effective design in quasiresonant converter as C-TV power supply.
