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 IC.
Included PWM controller features integrated fixed oscillator,
under voltage lock out, leading edge blanking, optimized gate
turn-on/turn-off driver, thermal shut down protection, over
voltage protection, and temperature compensated precision
current sources for loop compensation and fault protection
circuitry. compared to discrete MOSFET and controller or
RCC switching converter solution, a Fairchild Power
Switch(FPS) can reduce 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 cost effective LCD monitor power supply.
