Driver assistance required

[cantthinkofone]

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

Look in my sig for a list of vendors

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

200 milliamp hours? Are we talking about batteries here?

Its 190ma driver.. but you can ask him for adj version..

X-Boost T-mini 190ma Constant Current LD Driver Circuit - $24.00 : Zero Lasers :beer:

sorry not mah, ma. anyway sinner how small is that? i need it to fit in a somewhat small host. thanks for the link

 

[sinner]

Fits in the back of aixiz module, IIRC 8x10mm

What kind of cells and how many? If it's over 5V, the cheap driver o-like sells would work. Any lower
and it would most likely have to be a boost driver of some kind such as the one sinner lined up for you.

It's running off of one 14500. Don't know the exact voltage.

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 wouldnt put that thing anywhere near a 520nm diode.

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
