Ease of Use with Few External Components
Supports Wide Input Range
The ICE2PCS02/G is a 8-pin wide input range controller
IC for active power factor correction converters. It is de-
Average Current Control
External Current and Voltage Loop Compensation 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.

•
Trimmed internal fixed Switching Frequency
(65kHz+5% at 25oC)
Direct sensing, Input Brown-Out Detection
with Hysteresis
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.

•
Short Startup(SoftStart) duration
Max Duty Cycle of 95% (at 25oC)
Trimmed Internal Reference Voltage (3V+2% at
25oC)
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.
