Default low output driver for red diode

I'd like to find out if there is currently a driver available (besided flexdrive v5) that could provide 450-500mA of current with one cell for red diode?



P.S. if there is no such thing what coulld I use with two cells?


Thank you very much in advance!

Default Re: low output driver for red diode

LM317 with 2 cells for sure ...somebody with more experiance with the latest drivers will better advise on a single cell .

Default Re: low output driver for red diode

Well, with the help of driver developers here I figured my options so far for one cell build are:

Blitzbuck v2 or v3 - will require replacing the potentiometer/resistor with another resistor to set the current (calculation available in respective thread).

X-drive v6 - lazereer sells 450 - 500mA versions.

FMT DRV V2 - thanks to the great manual provided I figured I could replace two resistors and set it to the necessary current.

In all cases (if I understood correctly) the diode will need to be isolated from the host (anodized heatsink or other).

Damn I been saying the groove 2 driver in like 3 or 4 threads for the red diodes... anybody

Heres the link he is like the fastest shipper, distance wise, yet here is the link. Creative Technology Lasers - Your source for diode lasers and laser modules at green, red and other wavelengths. you get to keep your heatsink and choose to ramp up that current tooo.

Default Re: low output driver for red diode

Jander, groove is a linear driver. Manual says Vin = Vout +1.2? For red that will run at 2.7-3V my Vin would have to be 4-4.2V. I was interested in one cell builds (3 - 3.7V only) I'd consider two cell builds as a last resort option.
