Features
Description
• Ease of Use with Few External Components
The ICE1PCS02/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
