OPEN SOURCE: IRON4D Driver
(1050 mA, single-cell, on-diode Mits 300 and 500 driver)

As mentioned in my previous thread about the Magic Polarity Correction Circuit (here) I want to make some of the neat things I've created over the years available for others to use/enjoy/ignore/whatever ;) Next in line is the IRON4D Mits diode driver. I am releasing the Eagle schematic and board files. They're free for anyone to do with as they see fit!

Benmw (through CajunLasers) briefly had them for sale (with my blessing) here:

They use AMC7135 chips, and can be soldered right on to the diode pins. They work great for Mits 300 and 500 diodes. They default to 1050 mA, but you can leave a chip off and make them 700 mA (or stack two configured that way for 1400 mA).

Enjoy!

After just getting into LEDs , I was thinking about using those 350ma chips on laser drivers. Looks like I wasn't alone.

Very nice rhd. Another great design. I still need to try the reverse polarity design.
 
Good job, RHD . . .

Another nice thing about the AMC 7135 IC is that it has very little voltage drop (~0.15 VDC),

and thermally protected. It does have a 6 VDC maximum input voltage.

This enables it to be used with one #18650 cell easily.

The IC's are also available in 380ma versions for different combinations.

Thanks;

I love all of these open source drivers! None of them are what i need though :(

I have been looking for a labby driver capable of 2amps + for a long time, and it needs to be able to take a 12v input.

A larger size is preferable for heatsinking purposes.

Anyone can hook me up?

Thanks, and good job on the driver! Looks nice!

Yea but the info on the website says the output voltage is Vin - 1.5v, so if i put 12 volts in, i would get 10.5 volts out. Wouldn't that blow the diode?

It's a constant current driver, so when it says Vin - 1.5V it means that it can supply up to 10.5V.
 
These diodes are amazing. I used to have a MITS 500 with a 1050mA IRON4D that saw so many different hosts. Due to the elegance of a completed module, they are simple to transplant. Somebody start making these!

you can't.
Max input voltage of the AMC chip is 6V.

Excellent work as always RHD! :gj:
+1 for making it open-source. :beer:
