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, 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 R
converter solution, aFairchild 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 monitor power supply.
