Description
The Fairchild Power Switch(FPS) product family are specially designed for an off line SMPS with minimal external ponents. The Fairchild Power Switch(FPS) consists of a high voltage power Sense FET and a current mode PWM IC. Included PWM controller features the integrated fixed oscillator, the under voltage lockout, the optimized gate turn on/turn off driver, the thermal shut down protection, the over voltage protection, and the temperature pensated precision current sources for the loop pensation and the fault protection circuitry. pared to a discrete MOSFET and a controller or a RCC switching converter solution, a Fairchild Power Switch(FPS) can reduce the total ponent 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 monitor power supply.
