UCC28810EVM-003

Оценочный модуль контроллера светодиодного освещения UCC28810 с внутренним ШИМ затемнением.

The UCC28810EVM-003 is an 110W offline AC to DC LED current driver with power factor correction evaluation module . 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 LED's in series (58.5V max per string). The converter will provide 500mA 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 LED's. The boost, buck and DC half bridge multi transformer stages are included on a evaluation module single board assembly.
