Power Switch 1Out 5A 1.76Ω 4Pin4+Tab TO-220F Rail

Description

The Power SwitchFPS product family is specially designed for an off-line SMPS with minimal external components. The Fairchild Power SwitchFPS consists of a high voltage power SenseFET and a current mode PWM IC. Included PWM controller integrates the fixed frequency

oscillator, the under voltage lock-out, the leading edge blanking, the optimized gate turn-on/turn-off driver, the thermal shutdown protection, the over voltage protection, and the temperature compensated precision current sources for the loop compensation and the fault protection circuitry. Compared to a discrete MOSFET and a PWM controller or an RCCsolution, a Fairchild Power SwitchFPS can reduce the total component count, design size and weight and at the

same time increase efficiency, productivity, and system reliability. It has a basic platform well suited for the cost effective design in a flyback converter.
