Features
Description
• Ease of Use with Few External Components
The ICE2PCS04/G is a 8-pin wide input range controller
• Supports Wide Input Range
IC for active power factor correction converters. It is de-
• Average Current Control
signed for converters in boost topology, and requires few
• External Current and Voltage Loop Compensation external components. Its power supply is recommended
for Greater User Flexibility
to be provided by an external auxiliary supply which will
• Trimmed internal fixed Switching Frequency
(133kHz+5% at 25^oC)
switch on and off the IC.
The IC operates in the CCM with average current control,
• Direct sensing, Input Brown-Out Detection
and in DCM only under light load condition. The switching
with Hysteresis
frequency is trimmed and fixed internally at 133kHz. Both
