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
Thanks again to everyone trying to help identify my drivers.
Lexel messaged me and said the white one is for the TN42 (single XHP35) and the black one is for the TN40S (four XP-L HI).
I’m hoping to tackle the swaps this weekend. Both lights will need their battery carriers modified as well. I’m very excited to have Andúril in these two ThruNites.
I have Endermans 2nd Syniosbeam with your CFT-90, 48 amp driver. I’d like to know the allowable maximum and minimum input Voltages. Instead of powering it with the current 3S LiIon internal and external packs, I’d like to power it with either a 3S or 4S LiFeP04 pack. my LiFeP04 cells are charged to 3.55 and always settle after charging to about 3.47 or about 13.88 pack Voltage. Is this within the allowable range? I’d guess a 3S pack might be too low - 10.41 down to 9.3 pack Voltage.
