The Fairchild Power Switch(FPS) product family is specially
designed for an off-line SMPS with minimal external
components. The Fairchild Power Switch(FPS) consists of a
high voltage power SenseFET and a current mode PWM IC.
The integrated PWM controller includes the fixed oscillator,
the under voltage lock out, the leading edge blanking, the
optimized gate turn-on/turn-off driver, the thermal shut down
protection, the over voltage protection, and the temperature
compensated precision current sources for loop compensation
and fault protection circuitry. Compared to a discrete
MOSFET and a controller or a RCC switching converter
solutions, a Fairchild Power Switch(FPS) can reduce the total
number of components, design size, and weight, so it will
improve efficiency, productivity, and system reliability. It has
a basic platform well suited for cost-effective design in a
quasi-resonant converter as a C-TV power supply.
