Texas Instruments UCC28811 | Demoboard SLUU423

Description

This driver is comprised of three stages, including PFC stage, Buck stage, and Isolation stage. Both PFCand Buck stage operate in critical conduction mode. The isolation stage is a half-bridge resonant currentconverter with an option to adopt the multi-transformer design. A constant current is controlled by the Buckstage to provide 3 A to the LED strings, with output voltage range from 70 V to 85 V.
