UCC28810EVM-003 Evaluation Module



Texas Instruments' 110 W multiple string LED driver with universal line input and PFC

Texas Instruments UCC28810EVM-003 Evaluation Module Texas Instruments' UCC28810EVM-003 is a 110 W offline AC-to-DC LED current driver with power factor correction. This design utilizes a three stage approach with a universal input boost PFC stage, a low-side buck stage providing a controlled current source and a half-bridge DC transformer stage to provide isolation to four LED strings.

This converter was designed to support up to four strings of 15 high brightness LEDs in series (58.5 V max per string). The converter will provide 500 mA average current to each string. The design incorporates an interface for microprocessor control to allow for shutdown into a low power mode (<0.5 W) and PWM dimming of the LEDs. The boost, buck and DC half bridge multi-transformer stages are included on a UCC28810EVM-003 single board assembly.   UCC28810EVM-003 User's Guide
