Design files

Overview

This reference design uses the UCC28180 CCM PFC controller and the UCC256301 Wide Vin resonant controller as an LCC controller with an integrated driver. It provides up to 200-W constant current or constant voltage output from a universal AC input. An external analog dimming voltage signal can be applied to dynamically adjust output current for dimming LED loads.

Features
  • A universal AC input, 200-W output for LED loads
  • LCC resonant converter designed for wide output voltage range of 100 V to 200 V
  • External analog voltage signal smoothly controls LED dimming
  • Less than 10kHz frequency variation over full output range minimizes noise
  • Constant current or constant voltage output modes
