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 a
high voltage power SenseFET and a current mode PWM IC.
Included PWM controller features integrated fixed oscillator,
the under voltage lock out, the leading edge blanking, the
optimized gate turn-on/turn-off driver, the thermal shutdown
protection, the over voltage protection, and the temperature
compensated precision current sources for the loop
compensation and a fault protection circuitry. compared with
a discrete MOSFET and a controller or a 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 the cost
effective LCD monitor power supply.
