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. control 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
R
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 monitor power supply.
