200W PFC + LCC resonant converter reference design for LED lighting


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.

  • A universal AC input: 200-W output for LED loadsLCC resonant converter designed for wide output voltage range of 100 V to 200 VExternal analog voltage signal smoothly controls LED dimmingLess than 10kHz frequency variation over full output range minimizes noiseConstant current or constant voltage output modes
