Infineon 320 W Multichannel High-Power LED Driver Engineering Report
Engineering report for a 320W 4-channel LED driver using ICL5102 PFC/LLC and ILD8150 buck controllers, featuring universal AC input and high efficiency for lighting applications.
Overview
This engineering report describes a 320 W multichannel high-power LED driver reference design. It utilizes the Infineon ICL5102 PFC and half-bridge combo controller for the AC-DC pre-stage, delivering a constant 73.5 V DC output. The secondary stage consists of four ILD8150 DC-DC buck reference boards providing constant current output up to 1.5 A per channel. The document includes technical specifications, schematics, PCB layout diagrams, a complete bill of materials, and performance measurements including efficiency, power factor, and thermal characteristics across a 90 V to 305 V AC input range.
Use Cases
- High-power LED lighting
- Commercial lighting systems
- Industrial lighting solutions
