Hey guys. I need a driver for a custom build I'm doing. I'm powering an osram 520 and I would like it to be at 200mah. I can't seem to find where to get drivers of my specification. They all minimum at like 400mah

its not the current you should be worried about, its the Vf of the diode that will be a major determining factor.

Lithium cells are 3.6 - 4.2V apiece. It's probably best to go with a boost driver. If you can't find any boost
drivers to your liking, let me know. I might be able to modify one to do exactly what you want.

I don't mind price and would expect myself to either go good or not get one at all. That 190 should push the diode to a crisp 80mw
