ICE1CS02GXUMA2

Overview

The ICE1CS02GXUMA2 is a Combi PFC/PWM controller from Infineon Technologies, designed for high-performance power factor correction and pulse-width modulation in switch-mode power supplies. It integrates continuous conduction mode (CCM) PFC control with primary-side regulation capabilities. The device operates at a switching frequency of 65 kHz and utilizes an 8-DSO package configuration for surface-mount applications.

Feature Summary

• Integrates combined power factor correction and PWM control functions within a single IC
• Supports continuous conduction mode (CCM) operation for efficient energy transfer
• Features primary-side regulation architecture to reduce component count
• Designed for high-power-factor applications in AC/DC conversion systems

Applications

• High-performance AC/DC power adapters
• Computer and peripheral power supplies
• Industrial power supply units requiring high power factor
• Consumer electronics with strict efficiency standards

Procurement Notes

Verify the specific ordering code suffix against the latest Infineon datasheet to ensure compatibility with required packaging and tape-and-reel specifications. Confirm that the GXUMA2 variant matches the intended assembly process and environmental compliance requirements for the target application.

Selection Notes

Select this component when a single-chip solution for both PFC and PWM control is required to minimize board space and design complexity. Ensure the application demands CCM operation and can accommodate the 65 kHz switching frequency constraints associated with this controller family.

Part Context

This part belongs to Infineon's Combi PFC/PWM controller series, which merges traditional separate PFC and PWM stages into one integrated circuit. The ICE1CS02G variant represents a specific package and reel configuration within this lineage, aimed at simplifying the design of high-efficiency power converters.

Replacement Considerations

The ICE1CS02GXUMA2 has been discontinued. Official replacement devices include the ICE1CS02G and other variants within the same Combi PFC/PWM family. Verify pinout and electrical parameter compatibility before substitution.
