The organization, such as it is, is based loosely on driver type and then size. There’s a fair amount io duplication now but I have no wish to delete links without a request from the author or notification of a nonfunctional link. Many of these drivers are used for many different LEDs often with different voltages and all you do to use a different voltage led is look for where to put the Zener diode and 200 ohm resistor. It can certainly get overwhelming and reorganization is not unlikely but it’s assumed that if you have a question you will ask it and it will get answered. Most authors are good about starting threads to discuss the finer points so that such details aren’t buried here but it still happens. Such is the internet.

If someone would like to assume responsibility for this thread, change the format to table form, or whatever. I’d be happy to copy the entire OP in edit mode and send it as a pm. You would then be able to start anew with a blank thread. Maybe SB could figure out a way for another member to access/edit the op instead. IDK.

I was looking for this 2 things:
- high current single 18650 driver for XML2 (4.2V in and ~3.2v out, up to 8A but I would be thrilled with 6A) and
- high current dual 18650 driver for MTG2/XHP type leds (8.4V in, 6V out)

I selected this 5 boards:
9A Zener Modified MT-G2 Driver copy
16mm 12×7135 Slave copy
BLF 17DD-Zener Revision 2 copy
BLF17-Linear-Z copy
17mm A17DD-SO8 w/ ALT LAYOUT v043 copy

no particular light in mind but I prefer them to be 17mm dia (first one is larger, I know, but I did not find 17mm alternative) and AttinyA13 based drivers so I could flash modes.

I’d like a 10mm single 7135 driver board with no other components.

The idea is a super simple, 350/380 mA ON-OFF driver for a 10440 keychain light.

Hows this?
BLF Teeny10 Single 7135 only

2 layer board of 0.4×0.4 inches (10×10mm). $0.80 for three.

Guys, check my work

Wow, thanks for the work Warhawk, this is exactly what I’ve been looking for.

Just one question though, is the AMC7135 the only component one needs for this to work?

I’ve heard mention that an SMD cap such as a 16 V 10 uF is required also?

Nah…the LDO regulator (the 7135) is fine, the cap is for input/output smoothing, from a battery power source it shouldn’t be an issue

For both lights I would choose the A17DD-SO8, for the last one with a zener diode.
One sided, no 7135 chips, the FET is widely available and high current depending on battery.

OK, thanks for your input fingers, in my country actually it is not that easy to find SMD stuff if you want to buy 1 piece so I have to check first what components I can get, fingers crossed :bigsmile: …

Here are some 10mm & 12mm Single-Sided FET drivers.  The 10mm has been built and tested thoroughly, both inside and outside of a flashlight.  These give you all of the performance of "big" FET driver in a tiny package, while staying single-sided.

12mm

Nice work! Two questions:

-A very useful size for a couple of AAA-flashlights (Ultrafire M5, Ultrafire LZZ-06 and clones) is 11mm as well, can you make that one too?

-I do not have the knowledge to sort that out, can anyone find out an ebay-link to a LFPAK33 FET for this driver? I can not judge if one is suitable, and all I seem to find are ones that are over 3 dollars each.

The 12mm board is just a fluffed up version of the 10mm one, so it can be ground down to whatever size you need, down to the 10mm original size.

I know, and making and uploading a 11mm version if many flashlights use that size is still a good idea Smile

For anyone else I'd say no, but for you--I'll do it. Wink

It is already done, but Oshpark's system is having trouble again.  I'll try uploading again later.

Like Dale said, I'd go with the PSMN2R4-30MLDX.

djozz, are you sure about the Ultrafire LZZ-06 driver being 11mm, my Jexree Mini that i thought was as far as the body & head goes (they have only different reflectors) would be the exact same light is a 11,6mm driver.

I looked up this FET on Ebay and found no sellers that sell them for less than 3 dollars a piece plus $4.50 shipping Sad

To search Ebay succesfully I -unfortunately- was forced to look into all those different FET-packages Tired . In the end I found this graphic somewhere in a NXP pdf. Perhaps this saves some other folks a bit of what I have gone through:

I would have to take another look at it when I'm home.

Ok, found it. I looked into an old thread of mine: http://budgetlightforum.com/node/29825 and the driver of the LZZ-06 is even 13mm (press-fit), I got it all wrong, I remembered that the driver that I used was a mm too narrow, but it was a 12mm board that I used, not 10. Sorry Richard for doing the work, I promise that will keep looking out for a 11mm driver flashlight to build this 11m board in Embarassed.

Ok, that is interesting, that means they are more different than i thought.

The only difference i thought was the that the LZZ-06 had a OP reflector & the Jexree Mini had a SMO one.

I ordered the 12. (They charge by board area, and free shipping! Wow)
Now how do I order the FET. I assume I can get the rest off a Nanjg.

No, this uses the smaller version of the attiny13. Also the resistors and caps are 0603, some Nanjg drivers use 0805.

djozz, I spoke with Mouser today and was told they have offices in Munich and the UK, so you should be able to order the FET from Mouser there in Europe and not acquire the big shipping charges. As I recall, this should be just under a dollar apiece. Providing EU Mouser has them, of course. Digikey should be similar.

eu.mouser.com has them for .83Euro? Mouser-onderdeelnr.771-PSMN2R4-30MLDX

OK, so 13mm instead of 11mm?  If we're going all the way up to 13mm, then I might space things out a little bit more so it's a little easier to assemble.

If you are expanding it to 13mm, do you think it would be possible to fit the 7135 on there also?

I have been studying wights 15mm driver single sided FET+7135 that is sandable to 14mm, he used the SSU of course, and if you use the LFPAK33+0603 smd components+ the attiny13a-mmu i hope it could fit Smile

The light i would like to use it in, is of course the Jexree Mini, for that it would have to be sandable to 12mm, and it would fit djozz Ultrafire LZZ-06 also.

Sorry djozz, i was wrong about the 11,6mm driver in the Jexree Mini, i must have mis calibrated my caliper, it is a 12mm driver.

One very nice thing about this MTN-12DD is that if & when RMM starts to sell these single sided 12mm fet drivers, those plus an XP-L on an 10mm sinkpad is a total drop in Big Smile for the very nice 10440 host the 5$ Jexree Mini :bigsmile: Can you say ~1000 lumens at start from some very affordable parts Wink

Richard you really should considering selling that combo as a quick and relatively easy modded light in your store, there are not many 10440 hosts that can take a DD driven XP-L but this one can, and i bet you can sell a bundle of them Wink and with a sane shortish turbo timer they should be quite safe even.

I think that what would be more feasible on a 12mm would be pads where you could air wire a 7135 if desired instead of having it mount on the actual board.  There isn't room for it on the board.

Ok, good to know and thanks for checking out if it worked Smile

But pads is almost as good :bigsmile: there is more room to add height than building up the spring side with components, because with something like with wight’s fet+7135 12mm driver it leaves less than 1mm in the tube with the spring fully compressed.

If you can do a 12mm or 13mm sandable to 12mm with pads for airwireing the 7135, please do Wink

As far as i understand, if we don’t install the 7135 it should work just like the MTN-12DD.

Exactly.  I never liked having any components or having to jumper over stuff on the battery side.  I also didn't like the compromise of the attiny10/PIC versions, but the LFPAK33+attiny13a-MMU are an awesome combination for a tiny driver like this.

Smile Yeah i agree, i felt slightly uneasy about components sticking down in the tube & out from the exposed driver when they would change battery, my plan from early on was to find a tiny light i could mod to very bright, & do it so safe i could gift it to family members and not worry they short something on exposed components for example.

And a single sided driver makes it much more foolproof Smile and it will look stock, before you turn it on that is Wink

I will still probably build one Jexree Mini version with a attiny13a-ssu, just so i can more easy test various firmware set ups to see what i really like in a twisty with that much power.

You might want to add this one to the OP. Wink  Over the past few months, I've been slowly working on an update to the original BLF SRK FET driver (design by Mattaus; development ideas from Comfychair and many others).

  • Added more LED pads
  • Added optional 7135 on secondary PWM channel
  • Added optional LDO for 2S+ use
