52 W Low-Cost Two-Stage LED Driver Based on ICL5102 Engineering Report
Engineering report for a 52 W non-dimmable LED driver using the ICL5102 combo controller, featuring a PFC and open-loop LCC design with high efficiency and tight current spread.
Overview
This engineering report describes a 52 W reference design for a non-dimmable LED driver based on the Infineon ICL5102 integrated combo controller. The design employs a two-stage architecture consisting of a boost PFC and an open-loop LCC resonant half-bridge. By utilizing high-frequency operation (up to 250 kHz) and an integrated resonant transformer, the design achieves significant cost reduction while maintaining a tight LED current tolerance of ±10%. The driver supports an input range of 198 V AC to 264 V AC and provides three selectable output current settings for LED loads between 20 V and 52 V. Key performance metrics include system efficiency up to 92.5% and THD below 10%. The document provides full schematics, PCB layout, bill of materials, and detailed thermal and EMI performance analysis.
Use Cases
- Non-dimmable LED lighting applications
- High-efficiency indoor LED drivers
- Cost-optimized two-stage power supplies
- PFC and resonant converter reference designs
