Description
The ICE2PCS01/G is a 8-pin 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.
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 exter-
nal to allow full user control.
There are various protection features incorporated to en-
sure safe system operation conditions. The internal refer-
ence is trimmed (3V+2%) to ensure precise protection and
control level. The device has a fast startup time with con-
trolled peak start up current.
