CCM PFC controller for power supplies
The Infineon ICE3PCS03GXUMA1 is a power factor correction controller operating in Continuous Conduction Mode (CCM). It is designed for active PFC stages in AC-DC power supplies, typically placed between the bridge rectifier and the bulk capacitor to shape the input current waveform to follow the line voltage. The controller accepts a supply rail from 11V to 25V and draws 380 µA during startup.
Package and thermal considerations
Operating temperature range spans -25°C to 125°C, covering industrial ambient conditions. The 125°C junction limit allows the controller to sit near hot magnetics or a heatsink without derating.
Sourcing and compliance
The ICE3PCS03GXUMA1 is an active Infineon part with no announced end-of-life. It is available in Tape & Reel (TR) or Cut Tape (CT) packaging. ROHS3 compliant.
