Description
The ICE2PCS02/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 trimmed and fixed internally at 65kHz. Both
current and voltage loop compensations are done exter-
nally 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
output control level.
