Overview

This engineering report describes the REF-XDPL8210-U35W, a 35W digitally configurable constant current LED driver reference design. It utilizes the XDPL8210 High Power Factor (HPF) flyback controller and the CDM10VD isolated 0-10V dimming interface IC. The design supports a universal AC input range of 90 Vrms to 305 Vrms and an output range of 18V to 54V. It features primary-side regulation (PSR), high efficiency through Quasi-Resonant (QR) mode, and low standby power (<180mW) with dim-to-off functionality. The document includes detailed electrical specifications, schematics, PCB layout, performance data, and a full bill of materials.

Use Cases

  • Isolated constant current LED drivers
  • Commercial and industrial indoor lighting
  • Dimmable LED luminaires
  • UL1310 Class 2 lighting designs
  • High efficiency power supplies with dimming interface
