Texas Instruments UCC28180DR | Demoboard PMP20946
200W PFC + LCC resonant converter reference design for LED lighting
Overview
| Topology | LLC Resonant Converter |
| Input voltage | 108-305 V |
| Switching frequency | 18-250 kHz |
| Output 1 | 200 V / 1 A |
| IC revision | A |
Description
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
Typical applications
- Server and Desktop Power Supplies / Flat Panel (PDP, LCD, and LED) TVs
- Industrial Power Supplies (DIN Rail)
- White Good Appliances (Air Conditioners,Refrigerators)
- Universal AC Input, CCM Boost PFC Converters in 100-W to Few-kW Range
