[Leo] looked at the WS2811 LED driver, but found that the low drive current and the 8-bit PWM output failed to tick either of those boxes. [Leo] solved both problems by using two of the three PWM ...

Measuring the latter allows a constant power load mode (as power = current * voltage). In his article, [Kerry] shows that he can simulate a load of up to 200W.

Do you want to power a group of lighting LEDs? Here we present a handy solution to provide extremely accurate and stable ...
