Features
Description
• Continuous current operation mode PFC
The ICE3PCS01G is a 14-pins wide input range controller
• Wide input range of Vcc up to 25V
IC for active power factor correction converters. It is de-
• Programmable boost follower step level according signed for converters in boost topology, and requires few

switch on and off the IC.
• Accurate brown-out protection threshold
• External current loop compensation for greater
user flexibility
• Open loop protection
• Second over bulk voltage protection
• PFC enable function
• Separate signal and power ground pins
• Maximum duty cycle of 95% (typical)
