As usual Richard, you were 100% correct! Thanks for your help. I removed the 7135, cut off the centre leg, added a tiny piece of kapton tape to the board then bent the two remaining pins slightly down so they still had contact even with the kapton tape underneath. Battery back in and all is working perfectly! Thanks again!
Has anyone used this driver with an mtg2? If used on hi, will it regulate to a good usable level? I’m making a light for my grandfather and I don’t want him to have to worry about remembering how to deal with temperature.
Correct me if I’m wrong but I didn’t think you could zener mod this driver for use with 6V emitters???
Idk. I would like to know…
Has anyone tried this?
I don’t think there aren’t any traces for zener components…
From a hardware standpoint, couldn’t you add a zener to dump the voltage to the mcu and swap the protection diode with a resistor? Like a qlite driver… I might mess with the complicated firmware though?
Do it old school and cut some traces and air wire it.
Just kidding.
Hey… I’m not afraid! :disguised_face:
You could zener mod it, but you'll burn up the 7135 chips, especially the single channel 7135 chip, in a hurry. Not recommended. The duty cycle would have to be greatly reduced on the single 7135 chip, which would require a firmware change.
Ya. That’s what I was afraid of… Thanks for the information!
Is there any chance some form of this driver could be made as a 10 mm driver in the future?
Can anyone tell me what approximate amps I should expect this driver to pull in FET/DD while powering a single XP-L HI?
I’m trying to decide if 30Qs would be worth getting over my current GAs.
I depends largely on the total resistance of your circuit, but with a good bypassed tailcap spring and GA I would expect around 5A. You might get 0.5A-1A more from a 30Q.
Yeah, the spring would be bypassed. Hmmm…that doesn’t seem like it would be a huge visible impact. That being said, 30Qs are cheap enough to pick up down the line and see for myself.
Thanks for the input RMM!
Found out something interesting last night! This driver works with the PD68 2 LED lighted tailcap!!! Stock driver and basic tailcap.
I consider this a win and may make choking the price of a few more of the down easier!

So how does the thermal regulation work? It steps down a full level (of the 24 programmable modes)? Or it just dynamically decreases the PWM to maintain their thermal target but can do it in a far more granular fashion than the programmable levels?
Not sure how it works, very granular though. The only change I would like to see is mode reversal with a longer press.
Is there any plans to develop the same driver without the FET/DD option?
The PID is the main feature that makes it stand out from most drivers but this is not available in a standard linear driver.
Ultimately, would this driver be safe to use on a single Nichia 219C R9050 in a 1 x 18650 build. I am reading that the Nichia 219C should not be run on DD as it can easily overheat.
Thanks
Grrrr, I just got up from my night shift nap. This one i actually knew.
We use to goof around with it in the old IRC cjat rooms using different open source chat clients.
Oh well... early bird gets the worm.
Congrats.
When can I purchase?
