Do you have any suggestions for interesting topics about boost driver efficiency I can read, to learn more?

Here are a couple of pointers:

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…

Buck and Boost Drivers, Testing, Modding, and Discussion (Pic Heavy)

This post is intended for me to document all of the modding and testing I have been doing on various buck and boost drivers I have been playing with lately. For now I am only posting the raw data and some comments on the Kaidomain boost drivers, I will update the OP with more as results come in and I get time. Kaidomain H1-A 20mm “6V” Boost Driver This driver is intended to run an XHP50.2 at approximately 3A output. It is moddable to triple emitter voltages by changing resistor R1 to a higher …
