Description
The Fairchild Power Switch(FPS) product family are
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. 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 compensated precision current sources for the
loop compensation and the fault protection circuitry.
Compared to a discrete MOSFET and a controller or a RCC
switching converter solution, a Fairchild Power Switch(FPS)
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 monitor power supply.
