Description
FSD1000 is a Fairchild Power Switch (FPS) that is specially
designed for SMPS of personal computer. This device is a
high voltage power SenseFET combined with two PWM
controllers in a single monolithic device; One is for main power
and the other is for auxiliary power. The PWM controllers
feature
integrated
oscillator,
under
voltage
lockout,
optimized gate driver and temperature compensated precise
current sources for the loop compensation. This device also
includes various fault protection circuits such as line under/
over voltage lock out, over voltage protection, over load
protection and over temperature protection. Compared with
discrete MOSFET and PWM controller solution, FSD1000
can reduce total cost, component count, size and weight
simultaneously
increasing
efficiency,
productivity
and
system reliability
