Normally, when a project calls for addressable LEDs, we just throw a strip of WS2812s ... [Leo] looked at the WS2811 LED driver, but found that the low drive current and the 8-bit PWM output ...

To make things even more even there’s a slew of constant current LED driver chips out there that can be had for a song. But do you have any idea how those constant current circuits work?

Powered by high-quality constant-current power LED drivers which are rated for 50 to 60Hz at 120-277V input, produce less than 20% THD, and have a power factor of .90 to 1.00 By downloading any ...
