Lexels driver compilation

Is it possible to build it myself with your pcb and list of parts and program code? Small 6A boost driver is very useful for me. Thank you lexel. It seem some people like you, loneoceans, schoki is making such a driver, but so far i only see loneoceans with working design and flashlight. I am hope to build one myself.

Mtn e is currently making and selling a boost driver, but it is only 17mm and for clicky lights at the moment. Bigger sizes and e-switch versions will be sold soon.

Thank you jasonww! Is it this driver?

I think I may buy one. But I will like to try the 6A version made by lexel since it is much more powerful at 6A compare to 4.2A.

yes a lot depends on the used Bost chip and thermal cooling, on my driver I would strongly suggest to pot around the Boost chip with aluminum oxide glue
you could try the same on MTN driver

Basically whats limiting output current atm is thermal properties of the board

4.2A? That must be due to its small 17mm size (along with the 1.3A 12v output). The bigger ones are 6A just like Lexels (12v also goes up to 2.5A-3A). Roughly 50W seems to be the most you can get from these smallish sized boost drivers.

Lexel, can your 24mm drivers be sanded down to 23mm?
I have the Amutorch VG10 that takes a 23mm driver, and I guess one of yours would be good to fit in, if I can sand it to 23mm! BTW, will it work fine with:
a) Forward Clicky Switch
b) OSRAM KW CSLNM1.TG – 1mm2

Thanks in advance!

BTW, about the driver for the BlitzWolf BW-ET1, I will let it stay still until I get a good solution! Thanks for your answers, though :wink:

Buck driver easily sand down
the FET DD you may be careful with component side as then some are pretty close to the edge like 1mm

for 2S battery configuration a Buck regulated is possible but not yet for 1S

Hum…I guess I will want a FET DD (like the ones you sold me before), because I will use it just for one 18650 cell and clicky switch on the tail.
Am I correct in this choice?

If needed I can sand/file the host a little bit (on the inside), but there is few space. I guess using a 24mm driver will be better than using a 22 mm one, as there is not retaining ring nor “pill”.

1mm² Oslon needs regulated output or will burn
e-switch or clicky is just UI, if the LED works with battery is on DD an equasion between
battery voltage sag + conduction voltage drop
and
LED voltage

when both is equal you get a current which drops with battery charge status constantly

a battery with higher internal resistance has more sag, but this wont do the trick on an led with that low forwqard voltage and to about 4A limited max current

What driver will be suitable for driving an osram cslpm1.tg at 7 amps in a convoy L2

30mm buck as shown in first post, its listed under L6

Will it fit in an L2 though or only L6?

The L6 has 30mm driver and the L2 has 20mm. Or a very early L2 has 17mm.

I have also a 20mm Buck driver for L2, likely retaining ring needs to be adjusted in inner diameter

Can it be set for max 5 amp?(flat white)

i’m btw really enjoying my convoy L6 with 8amp driver. Thanks Lexel!

Buck drivers get always set to the desired current

when I search for this LED I get only a non 3535 package found

20mm special for C8F 21700

new 1S 17mm version, for e-switch added R_ind and Ind. Pad, 209mil SOIC support

Planned
35mm Haikelite MT02 Boost driver

How has the progress been with the boost drivers?
Are they still planned for a future release?

I am waiting eagerly for this boost driver. Right now i order parts to make my own gxb172 but it is good to be able to buy one from you directly!

I hope next year with the apartment finally done and settled I get enough time to do a lot testing on new driver architectures

right now I am still trying to catch up with orders getting the delivery time back to a short one
