STEVAL-LLL004V1: 500 mA @ 80V Max, 85 ~ 265V in

Summary

The STEVAL–LLL004V1 is a digitally controlled constant current LED driver. The PFC stage and the two DC-DC converters are designed to work in transition mode to optimize efficiency.

The LED driver can deliver 75 W output power. It can dim the LEDs down to 0.5% of the maximum brightness level through both analog and digital approaches. The operation is flicker free across the entire dimming range using either of the dimming techniques. The board features high efficiency, a power factor almost equal to one, and a low THD percentage 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.
