Essentially simple when you’re not using the kitchen sink stuff…
This one was in the BTU Shocker with triple XP-L emitters in parallel, hence the triple 18ga wires at each LED terminal. I replaced it with a Zener modified version to run 9V MT-G2 emitters.
Thanks for the photo!
Looks pretty sweet. Need to get some of these ordered in the next couple of weeks.
I just ordered some to use in a Roche LS01. Hopefully they’ll trim down to 21mm just fine.
I was initially thrown off by all the extra resistor pads; it didn’t cross my mind that they didn’t all need to be populated.
Those extra pads are the kitchen sink spoken of earlier. For thermal and such. I don’t really understand that aspect of it, but as a normal driver it works just fine. Maybe I’ll figure out just what the kitchen sink has to do with lighting and implement some good “clean” fun. 
Has anyone used the pulldown resistor for the OTC? What resistor-value range are we talking about? My cap is taking too long to drain.
I remember seeing a discussion about it somewhere, but now I can’t find it.
Does this look right? I can’t get it to work properly, no matter what firmware I use it gets stuck on turbo. I’ve used a zener and replaced the diode with a 200ohm resistor.
I’m using it for a MT-G2 build.
Stuck on turbo? as if it is going DD and bypassing the driver?
As in, I can cycle through modes but when I get into turbo I can’t get out
wow. That’s very strange. My gut tells me it has to be something with the firmware, but you’ve already tried different ones so I’m stumped. Hopefully somebody else can chime in.
Think I’ll try another firmware tonight. Does C1 need to move?
Managed to get this working in a Nitecore MT40 
Still not 100% happy with the firmware but I’m always adjusting the modes anyway.
Any trick to get it working? Did you move the C1 cap? I'm about to convert one to a zener.
I'm surprised there hasn't been more posts on this driver - seems awesome. I'm gonna try a zener mod version to go in a Roche LS01 w/XHP-70.
Nope just left the board with the same layout as above the trick seems to be getting the firmware right.
Without the zener (went into a SupFire F3-L2 with BLF-A6 firmware):
Why are you using a 47k resistor for R1?
Will the NXP PSMN3R0-30YLDX N-Channel MOSFET - LFPAK56 work on this driver? I do not have the FET in the photo above…

Yes - think that was the original one on the parts list? Anyway it would work fine, accept not the best for high amps with triple LED's in parallel for example. I use the SIR800DP pretty much all the time now though. Probably no noticeable difference for single LED applications.
Is there really a noticeable difference for any set up? Or is it just a measurable difference?
I would therefore assume any of the drivers in this series use the same parts + the 7135?
Thanks Matt
Yes. There are a bunch if extra pads on this one but you can just leave them empty, they aren’t necessary for normal function
