Anybody use this driver?

[DTR]

I have a guy that got some 445 diodes from me and wants to use this driver.
5.5V 2.5A Power Driver for 500mW-1W 445nm/447nm/450nm Blue Laser Diode | eBay

I am not familiar with it at all. It says "Step UP Circuit" but then says to use two Li-Ions in series.:thinking: Also it says constant voltage which worries me as well. Anybody have any experience with it?:beer:

I've seen those but never tried them before. The title makes it sound like a boost driver but the description makes it sound like a linear. And like you said it says constant voltage not current.
Id just reccomend your buyer to choose a different driver. There are smaller less expensive ones that we know more about then that one. I've contacted the eBay seller for you so Ill wait and see what he says also. :beer:

Well I did suggest that but he has them in hand and wants to try to make them work.:tinfoil:

Ok well then I guess he needs a test load or I'll wait on the sellers response . It looks like it has a voltage regulating ic aswell though but I'm not sure but it looks and sounds like a linear.

There's no inductor on that board, so it's not a boost driver.

Typical poor Chinese descriptions. That's all that's going on here.

That was the fist thing I noted to him. Damn sketchy sellers. I see he sold 26. I wonder how may of my poor little diodes went to heaven with those.:yabbmad:
