Product Summary

The ICE2PCS02G is an 8-pin wide input range controller IC for active power factor correction converters. The ICE2PCS02G 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. The ICE2PCS02G 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 externally to allow full user control.
