The STEVAL-LLL004V1 digitally controlled constant current LED driver reference design features a PFC stage and two DC-DC converters designed to work in transition mode (TM) for optimal efficiency. The LED driver can deliver 75 W output power and implements both analog and digital techniques for flicker free dimming down to 0.5% of the maximum brightness level. The board features high efficiency, a very high power factor above 0.97, and a low THD across wide input voltage and load conditions, thanks to the high performance ST power products and the advanced algorithms running on the 32-bit STM32F0 microcontroller. https://elecena.pl/product/16949434/steval-lll004v1-75-w-digitally-controlled-constant-current-led-driver-reference-design 2020-06-05 https://elecena.pl/product/16949434/steval-lll004v1-75-w-digitally-controlled-constant-current-led-driver-reference-design 2021-11-07 https://elecena.pl/product/16949434/steval-lll004v1-75-w-digitally-controlled-constant-current-led-driver-reference-design 2022-06-12 https://elecena.pl/product/16949434/steval-lll004v1-75-w-digitally-controlled-constant-current-led-driver-reference-design 2022-06-24 https://elecena.pl/product/16949434/steval-lll004v1-75-w-digitally-controlled-constant-current-led-driver-reference-design 2023-09-01 https://elecena.pl/product/16949434/steval-lll004v1-75-w-digitally-controlled-constant-current-led-driver-reference-design 2025-06-27
