Part Number : 3S0680RF
Function : Fairchild Power Switch(FPS)
Package : TO-3P-5L, TO-3PF-5L Type
Maker : Fairchild Semiconductor
Pinouts : 
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. controller IC features a trimmed 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 RCCswitching converter solution, a Fairchild Power Switch(FPS) can reduce total component count, design size, weight and at the same time increase & efficiency, productivity, and system reliability. It has a basic platform well suited for cost effective C-TV power supply.
Features
• Wide operatimg frequency range up to (150kHz)
• Pulse by pulse over current limiting
