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
Hi.i want to make anther order if posible soo i want a driver for :trunite tn42 xhp 35 led. If u can help me,please tell me the price and i will send u via paypal
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!
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
So this would require hardware modification of your driver ? + anduril modification to support tint ramping. Would you be able to provide this to sell ? Or will I need to mod the firmware myself ? (Not sure I am capable, I am big noob in that regard).
Also this driver is only compatible with the mf01, not mf01s right ?, is this due to body difference (driver cavity depth ?), cell carier modability or something else ?
I don’t have the flashlight so I’m checking if this is viable to decide to buy it or not.
driver is quite easy removing one trace and wire it separately from the input resistor
looking at the lantern Anduril config file it seems it uses only one ramp register and rest is done with separate tint mixing code
so replacing that should be possible but has to be tested
Thanks for your reply Lexel!
If it works, I will use the driver in a sort of “piggy back” way, incorporated in the structure of this driver:
It will be connected to the PCB and to the switch it has there. For your explanation, could I use it without those 3 pieces on the bottom side in this configuration? I am concerned about the small space I have to fit the driver on that hole…
