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, weight and at the same time increase efficiency,
productivity, and system reliability. It is well suited for cost-effective design of flyback converters.
