17mm & 20/26/27mm single-sided DD/FET driver release: A17DD-SO8 / A20DD-SO8 / etc

If I recall correctly, RMM is planning to sell these soon, after he gets time to build them. Might be a little while though.

Otherwise, it’s possible someone in this thread might be willing to help. I suspect, if that’s the case, they’ll probably PM you.

And it was a pain to get it on there too! I wanted to keep it single sided so that was the only option I had at the time. As others have mentioned, add a little fresh solder to it and your iron should be able to pull it right off.

Hah, when I ordered I didn’t realize that the star used for “no memory” was on the same pin used for OTC. I’ve been meaning to reflash it with no memory for months.

I figure I’ll add some other features too, while I’m at it. :slight_smile:
(short/med/long presses, battery check mode, blinkies, etc)

Of course, I could also try to rig up some other sort of clip or connector, to flash in tighter spaces or when the two unused pins are blocked. The current OTC location is physically the best spot, it just blocks the SOIC clip.

Look what came in today! I should really start looking into rework stations… :stuck_out_tongue:

Chazzy, you’re gonna have to change your sig line…that lackadaisical response is about to take a twist in perspective! :wink:

Chazzy i might have a 2008D hot air station in about a week for a nice price if interested ? if so ill pm u when i get it might ask $60 shipped retail says $80

Hehe, that always seem to be my go to sarcastic response. I don’t think I’ve ever been successful conveying sarcasm through text.

The main turn off for me right now is the grounding problem with the cheaper reflow stations. If I knew which wire goes where I would be fine purchasing one.

So errr, don’t order SiS414DN to use on this driver. I must have missed the fact that it’s actually PowerPAK 1212-8, a much smaller package than LFPAK56. That’s why the “package limited” values seemed so low!

Now I’m stuck w/ two of them (which I ordered for testing with the QX7136 over here)… maybe that’s an excuse to make a smaller driver of some type?

It’s slightly larger than SOT23 (and significantly higher performance IIRC). It appears that PowerPAK 1212-8 is also known as: LFPAK33, DFN3.3x3.3, PQFN08B, EDFN 3x3, TSDSON-8, Micro8 Leadless, and MLP08S according to this document from NXP.

There are even smaller modern power-MOSFET packages which might be good choices for the task you mentioned. It appears that there is a SOT-363 compatible footprint being used now which is referred to as things like “PowerPAK SC-70-6” and “UDFN2020-6” and probably other things. It’s more like 2x2 rather than 3.3x3.3. Maybe something in that size could be found the for the smallest DD drivers. That said, if the larger 3.3x3.3 pacakage fits it’s what I’d probably go with.

Thanks for the answer wight, i realized that it was larger myself after my post so i deleted it, i am glad you saw it before i did :slight_smile:

Of course if it would even be possible to make an even tighter 10mm FET driver i would be very interested, i have a bunch of small 10440 possible hosts coming that i just have :slight_smile: to somehow put a XP-L V6 and a tiny driver in, but i think the slimmer the driver could get the less modification i will probably have to do to make it work and leave more room for heatsinking.

What do you think of the SI5415AEDU-T1-GE3, would something like that work?
it is a 1,9mm x 3 mm PowerPAK-8 ChipFET Single

Or a PowerPAK SC-70-6 SIA414DJ-T1-GE3

If you would use the 3,3 x 3,3 what about A10DD-M8 as in “Micro8 solderless” and something that sounds similar to M80 and a FET DD driver in tiny aaa size packs a lot of BANG in a size of 2 M80’s J)

When I first built the Tiny10 FET the intention was for an Efest IMR10440 to run it at around 3A. But I was urged to test it with larger cells. As I recall it went up to almost 6A with bigger 18650 cells before I quit, wanting to use it in my favorite light and not kill it.

I have a new one in that light now that is pushing an XP-L V6 2C at 966 lumens from the Efest IMR10440 at 3.2A current draw. My cells are old, not fully charging anymore, so I have a couple of new ones on the way. Looking to get 1000 lumens from this 3” neck light. :slight_smile: (the 2502 FET is the one it uses, I think)

Hi Dale, yes you and your Texas Poker is a big inspiration in my pursuit to build something that small and powerful, + i just today found djozz second mod of the “LZZ-06” :LZZ-06 mod#2: XM-L2 T6 3C, BLF-tiny12 driver+FET, Efest 10440 V2 ***27 lumen/gram !!***
And i had already ordered one, nice looks like the possible host i wanted :slight_smile:

Besides the BLFTiny10-12DD i am also considering trying a QTC direct drive in a twisty to get some control and usable lower output, they should manage up to 10A.

I wonder i anyone have tried one in a 18650 twisty………

The A17DD-S08… NAKED!

How well do you know your drivers? Can you populate it like this, without looking at any cheat sheets? I must’ve done too many or something, because I CAN! lol

What did you use 2000 grit sandpaper to strip that?

1000 grit Carbide paper.

’course I can. :slight_smile:

Stylish!

I forget so much, so fast, it’s simply astonishing that I can look at this layout and know what goes where without even thinking about it. :slight_smile:

Just goes to show, priorities are always a key factor! lol LOVE this driver! It has greatly eased my process and the fit into a light is so simplified it’s almost like cheating.

Peer pressure begets another driver:

[WIP] 17mm DD+single-7135 driver - single sided & Dual-PWM compatible?

It looks ready to go to me. What are we using for moonlight with a single 7135 these days? I think you posted some good info in RMM’s store thread, but I’ve lost track.

What would be cool would be if an optional 15mm daughter board with 7135 to be attached to this great piece of work which would in effect keep the bottom flat for the retaining ring. That way maybe there is the possibility of adding up 4 or 5 7135's to suit one's needs.

Mattaus already made a 16mm daughter board which carries up to 6*7135. It’s in the OSH Park projects thread. Depending on the goals that is a good option.
