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) consists of a
high voltage power SenseFET and the current mode PWM con-
troller IC. The PWM controller includes an integrated fixed
oscillator, the under voltage lock out, the leading edge blanking
block, the optimized gate turn-on/turn-off driver, the thermal
shut down protection, the over voltage protection, the tempera-
ture compensated precision current sources for loop compensa-
tion and an fault protection circuit. Compared to just PWM
controller combined MosFET or R
tion, a Fairchild Power Switch(FPS) can reduce total compo-
nent price, design size, and weight,also simultaneously increase
efficiency, productivity, and system reliability. It has a simple
method of application well suited for cost down design in either
a flyback converter or a forward converter.
