ICL5102XUMA1

Overview

The ICL5102XUMA1 is a high-performance integrated two-stage controller designed for AC-DC LED lighting applications. It combines a Power Factor Correction (PFC) stage operating in Critical Conduction Mode (CrCM) and Discontinuous Conduction Mode (DCM) with a resonant half-bridge secondary stage, typically LLC or LCC topology. Packaged in PG-DSO-16, this component reduces external bill of materials and system footprint while delivering excellent power quality, high efficiency across wide load ranges, and superior EMI performance.

Feature Summary

• Integrated two-stage control combining PFC and resonant half-bridge functions to minimize external components
• Supports Critical Conduction Mode (CrCM) and Discontinuous Conduction Mode (DCM) for the PFC stage
• Optimized for high efficiency and low Total Harmonic Distortion (THD) in LED driver systems

Applications

• High-efficiency AC-DC LED lighting drivers
• Resonant half-bridge power supply designs
• Systems requiring reduced bill of materials and compact form factors

Procurement Notes

Verify the specific ordering suffix against official Infineon documentation to ensure correct tape-and-reel packaging configuration. Confirm that the device variant matches the required thermal and electrical specifications for the target application. Cross-reference the full part number with manufacturer datasheets to validate package type and pinout compatibility before integration into design schematics.

Selection Notes

Select this controller for applications demanding integrated PFC and resonant conversion without separate discrete controllers. It is suitable for designs prioritizing component count reduction and size optimization. Ensure the application supports CrCM/DCM PFC operation and resonant tank configurations compatible with the half-bridge output stage.

Part Context

The ICL5102XUMA1 belongs to Infineon’s portfolio of AC-DC LED driver ICs and controllers. It is categorized under mixed-signal control ICs specifically engineered for power factor correction and resonant topologies. This series targets the LED lighting market by offering digital-like performance through analog-integrated circuitry to enhance power quality and system reliability.

Replacement Considerations

Consult official Infineon substitution guides for verified alternatives. Generic cross-references are not recommended due to specific internal control logic and pinout dependencies inherent to the integrated two-stage architecture.
