Original ICE3PCS01G Marking 3PCS01 Standalone Power Factor Correction PFC IC for PSU PSU3300-01 PLUS1

The ICE3PCS01G is a 14-pins wide input range controller IC for active power factor correction converters. It is designed 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.
