Does this driver exist, or something like it?

There was a thread posted several years ago

http://laserpointerforums.com/f67/ddl-evolution-quest-single-cell-linear-red-driver-ic-62025.html

I'm looking for a driver that meets this spec. Preferably without going to a $20-25 Flexdrive on a $3 diode

I have a bunch and I would like to mount them in F23 hosts.

Pman had a suggestion on the Aixiz one, but I don't think a 10440 will give enough juice to power an 815/826/etc red with more than a trickle.
His measurements were about 185ma

But I've got a few on order to try.

Any help?
 





Shameless plug, but the blitzlinears could depending at what current you run at. Even at the full 1A output they only drop .7V, so I don't think running a red at a few hundred milliamps would be a big deal.
 
Thanks, size and power are great.

It will fit, but price still adds up for doing a lot of them. If I can't find another option, that will probably what I will use to get decent power from them. I'll just have to order a few at a time.

Actually the Blitz Linear is postive regulated and the reds AFAIK are case negative. I knew there was a reason it wasn't on my list. Too much work on a small host.

Didn't even think about that. I always forget those reds are case negative, one of the reasons I haven't used many of them- usually turns out to be too much of a hassle.
 
The one I'm sending you should do the trick with no problem, I hope it works out for you and I'm glad I could help. This is why I don't charge people here for things I get for free lol Pay it forward and help someone else

It wood bee hard to get below $16 using quality parts.

eFest LiMn 10440 will do 350mA.

I was thinking maybe a LED driver somewhere or similar

The thing that surprises me, there are TONS of low power red lasers on the market running off two AAA or two AA batteries. The lasers are dirt cheap, aren't any of these drivers capable or available that could push a little more power and current?

You said it was the Aixiz one, I'll have to test myself and try it.

but if it is their standard red driver then with two 10440 it does great, with a single 10440, not so much. Not enought overhead voltage from what I've been told. But thank you

There is no driver at all, only a tiny
resistor. Up the voltage a little more and
poff, no more laser.

AixiZ driver is also continuous positive

I know most are like that. but some have a bit more sophistication. I've seen a few with what appears to be actual drivers attached. THen again, it might just be that and a cap :)


Didn't know that about them being continuous +

Thanks for the warning. Maybe I'm reading it wrong but it sounds the oppostie in the notes.

2pcs Adjustable Current Laser Diode Driver 80 500mA w TTL | eBay

Laser Diode –ve is controlled by the circuit. (Note: for case +ve diodes the case cannot be grounded.)

this driver requires the diode to be electrically isolated if the diode if the diode is case+ve

amc7135?

Oops - Dummy me -

http://laserpointerforums.com/f39/fs-amc7135-drivers-68834.html

Are these still available from you or elsewhere?

I ordered a couple of these below, hoping I can push them a bit further than 1.5v and they will work but time will tell.
Found them yesterday while digging throuh pages of LED drivers

350~400mA Regulated LED Driver Circuit Board for DIY Flashlight (1.2~1.5V) - Free Shipping - DealExtreme

Not sure, but other than these and the AK007, I think they are the only LED drivers that fit that size host

If they don't work, at least I have some contact boards for whatever I need in that size :)

Otherwise I resort to a Flexdrive or equiv

OR a higher power vs of this - IF one comes out ???

You could make a single amc7135 driver with all of 2 or 3 components, get the boards from china for pennies a piece, and the chips for next to nothing as well--it wouldn't be hard, by any means.
 
Just discovering the AMC 7135 driver. Seems perfect

Thanks for the help.

Are these available in a small board with a 1 or 2 that anyone know of?

You ever have one of those Duh moments.

The more I look at the AMC 7135 the more it seems to be exactly what I'm looking for

And the more I look, the more obvious it seems - and the more threads I find - and the more stupid I look

Clueless I guess :) (and slow)
Maybe I'll go crawl in the corner now
