Nice stuff. Thumbs Up
I have no use for it though, unless it could output 6Volts on 3S battery config.

Must say though, those traces on the Sinkpad 12V XHP boards sure look flimsy.

The driver should do fine with 3S to 6V, but its current is with 6A Inductor nowhere near DD drivers,
maybe crank it up to 8A or so ask DEL what the inductor and Diode can do and if the capacitors need to be changed

I also worked on TN42 size

Got today some stuff in a Mouser parcel for TA and GT drivers

Just a little comparison from BLF MF02 Inductor with stock driver ones
could do this basically to all components of the Buck regulators current parts

O that’s interesting.
6 Amperes is enough for me, i’m thinking XHP50.2 with a 68mm 10° TIR in a Courui, but it has to be 34mm or less in diameter…

yeah for 6A I need to stack a 2. shottky diode

I asked DEL if more or other caps needed

What a big difference. I didn’t know what I was meant to be looking at for a second. Smile

How much current does this driver give to the led? 12V/2,5A like BLF GT? And if it is using with xhp 50/70?

I am not a modder just courious. You wrote that it will work with xhp 50/70.

The driver for MF02 XHP35 LED is 2.5A same as the GT, same UI
for XHP50/70 can be higher current

I am discussing with DEL the needed changes
So far Buck frequency changed from 800 to 500kHz
input and output caps doubled, the design already has pads to fit 2 caps instead one
Diode 3A to 5A
inductor from 6A to 15.5A

6-8A should be no problem to get to

If I understand correctly:
In currently state this “BLF GT” driver with 12V/2,5A can run a xhp35 about 2500lumens, xhp50.2 at 3600lm, 70.2 at 4400 lumens (from Texas Ace’s charts).

The modified version of this with 12V/6-8A can run a xhp50.2 at maximum (5000 lm) , 70.2 at 8500-9500 lumens at 6-8A. Maybe kill the xhp 50 at 8A, and will it kill a xhp35 already over 3A? So is is not recommended using this high current driver with xhp35?

The drivers are build for the current you ask for, so its like you want 2A or 4A no problem to change that on every order
Just going over 5A needs better parts that add cost

Keep in mind those current numbers are for keeping a high efficiency, of course you can get more out than 5A of the original design, but the efficiency goes down and heat up

Possibly interested. Not quite sure if I’ll keep the light or not yet.
But thanks for your commitment for the community!

Intrested for 1.

UI question.

Will this have the ramp stopping short of max, with double tap for turbo?

If so, roughly what would the % be when built for 8A xhp70.2?

Thinking I may have to get one of these along w/a couple more of the TA drivers.

The ramping can be short of 100% or be programmed to 100% as the Q8 as you wish

the code for GT is 201/255 for max ramping table

If no mod the battery carrier, Keep 2S2P.

Can be used in 6V for XHP50 or XHP70?

Sorry for my poor english.

You need to use a simple fet driver , the Mf-01 driver lexel builds can be used .

2S/2P carrier and 6V LED can be used with normal parts up to 5A with lowered buck frequency
with upgraded parts about 8A
of course this might be well enough for a XHP50.2, but rather poor for a XHP70.2

Those are the currents to stay safe well within specification of the parts, of course it is possible to get out more but then no guarantee to operate without any issues over a long time,
if you want it just lower the sense resistors as usual for buck/boost drivers

been busy yesterday and today

12 MF02 2.5A drivers
2 MF02 6A
1 TN42 and
1 TN40 12V 8A

I think this should show the carrier modification pretty well

I made a 30mm layout that could be extended in my board program to the nessesary size or grinding down the 42mm TN42
The Curoi should be 38.5mm, if the edge clearance is small the TN42 could fit

So I did further testing of the drivers

With 2.5A Output I get on my bench test LED XHP70.2 12.31V
This means 31.02W output
to get this output the driver draws 2.075A at 16.14V
33.49W

so we ge an efficiency of 92.6% for turbo
