Since I got a D4SV2 I’m a big fan of Andruil with 1634 and RGB LEDs.
Lexel, do you have any plans to migrate some of your drivers to that architecture eventually?

Thanks for your work Lexel! Just to let people know, this will be used in the LT Tool 25 and in some other 2xAA (soon to be 2×14500) flashlights !!

Thanks again and I’m sure other people will grab these too Wink

Can this driver be used to drive a UV LED in a Tool 25 with 2× 14500? Will it regulate the current until the batteries are depleted to 6V?

The FET has no current limitation, the small current resistors have current limiting function but no regulation and are only useable with 6V LEDs

I need one for my S42. Can you send me info on where I can buy one? I also have an issue with the charger in it. Can you replace this also?

Send Lexel a Personal Message with your driver request info. It’s the blue button under his name that says “Send PM”.

Okay, so I’ve pulled apart my MF01 driver (the buck one, v2.1) that I got from you; everything’s working fine, just re-wiring it. Just testing with the DMM and I seem to be getting 140-150 ohms between LED+ and LED-. Unsure if that’s expected behaviour; seems to be happening on both sets of emitter wires. Open to thoughts! I’m reflowing it now on a heating platform in case I’ve done something stupid somehow.

OR

Is it possible to get this image redone without the components on it, so I can trace and isolate?

Measuring this is no defect its just that the Shottky diode gets conductive by your DMM
they respond very fast and can deliver high currents but also have a quite considerable leak current

diode test shows me one side about 0.1V the other side 2.8V

a proper test would be a current-limited source of like 1A and then measure the current in both ways

Awesome, thanks mate. Was just re-doing my wiring on it, and got a short (thankfully tested before putting power to it), and have been chasing it down and then noticed that.

phew

The buck chip has no problem with shorted output, it will just leave you in the dark till its removed

Lexel what is the minimum input voltage that could be used for one of these larger boost drivers? Would it be possible to power an XPL with this using only 2 NIMH cells? If so what would be the maximum possible drive current for the LED?

Those drivers are specific for UVC LEDs its working fine with 8V and 500mA, the chips input switching limit is 1.2A so 8V 500mA is pretty much at its limit
its >3V input voltage so only lithium battery

Lexel has been “absent” for almost 2 weeks now.
Maybe it is better for you to send him a Personal Message to let him know about your request, so that he can see it when he returns!

Hello,
Would the MF01 driver with dual buck be able to support tint ramping ?

I see no problem modding one Buck side to be on another channel for tint ramping
for moonlight and low levels there would be a shared PWM pin putting the Bucks synchronous into a lower output

the more challenge is to look into Andurils Tint ramp code to add the Buck PWM channel to the existing 2 channel tint mixing
