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 dis-
crete MOSFET and controller or R
CC
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 design in PC SMPS with Power Saving function.
