ICE2PCS05XKLA1 Description

The ICE2PCS05/G is a 8-pin wide input range controllerIC for active power factor correction converters. It is de-signed for converters in boost topology, and requires fewexternal components. Its power supply is recommendedto be provided by an external auxiliary supply which willswitch on and off the IC.The IC operates in the CCM with average current control,and in DCM only under light load condition. The switchingfrequency is programmable by the resistor at pin 4. Bothcompensations for the current and voltage loop are exter-nal to allow full user control.There are various protection features incorporated to en-sure safe system operation conditions. The internal refer-ence is trimmed (3V+2%) to ensure precise protection andcontrol level. The device has a fast startup time with con-trolled peak start up current.85 ... 265 VAC EMI-Filter
