I need to be educated about LED drivers.

I did a description of the different types of drivers a while back. Maybe it can be useful to you:

Understanding the difference between Linear, Buck, Boost and Direct Drive drivers

A long time ago I promised I would do a topic to explain to the interested layman the difference between Linear, Buck, Boost and Direct Drive drivers. Well, here it is. Direct Drive [image] This is the simplest and cheapest design. As its name implies, it is a direct path to the LED, just like old incandescent flashlights. Sometimes there is a control chip and transistor to create modes (High, Low, Strobe, etc.) by rapidly switching ON and OFF the LED. That’s called PWM. This is used by peop…
