Description
The ICE3PCS03G is a 8-pins wide input range controller
IC for active power factor correction converters. It is de-
signed for converters in boost topology, and requires few
external components. Its power supply is recommended
to be provided by an external auxiliary supply which will
switch on and off the IC.
