Description
The ICE1PCS01/G is a 8-pin wide input range controller
IC for active power factor correction converters. It is designed 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.
The IC operates in the CCM with average current control,
and in DCM only under light load condition. The switching
frequency is programmable by the resistor at pin 4. Both
compensations for the current and voltage loop are external to allow full user control.
There are various protection features incorporated to ensure safe system operation conditions. Examples are
peak current limitation, brown-out protection and output
under voltage detection. The internal reference is trimmed
(5V+2%) to ensure precise protection and control level.
The device has an unique soft-start function which limits
the start up
