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…
Hey Lexel, i made payment 23rd May and last mth 16 Jun you said you should have them out soon. It’s been another month, and been messaging you past 2 weeks with no reply. Can you let me know what is going on?
I want to upgrade my L6. Will your 30mm buck driver work with 3 LifePO4 batteries (9.9V)? Additionally, is it current regulated? Can it be pushed to 9 amps?
I wonder if anyone can help me identify two Lexel drivers.
I ordered one for a ThruNite TN42 and one for a ThruNite TN40S, and I’ve managed to get them mixed up.
My TN42 is a single XHP35 HI emitter. My TN40S is four X-PL HI emitters.
I ordered these drivers several months apart, and they are slightly different in physical layout. They each have some unpopulated components.
I am not very knowledgeable in driver design. One obvious difference I can see is the values of resistors 8, 9, 10, and 11 on the non-spring sides. Perhaps that’s an easy clue?
I am currently out of town and have no DMM, clamp meter, or power supply. Can anyone tell which is which solely by physical differences?
I was just going off the description in the first post; my understanding is that the TN42 was always XHP35, so yep the white driver for boost - but my reading off what Lexel has written is that the black one is for the TN42, or a TN40S that has been modified to run XHP35s.
But you’re right - for a definitive answer, only Lexel can really answer.
3.3uH is always a larger current -> same ripple voltage for regulation
10uH 2.5A, 3.3 4-7A, 2.2uH 7-8A
Resistor values the same the smaller the combined resistor is the higher the current has to be for same voltage drop
left driver 47mOhms*4.5A=214mV
right 90mOhms*2.5A=230mV
