Led4power.com : LD-4 CC linear drivers, ILC-0/1 illuminated tailcaps, optics, MOSX, copper DTP MCPCBs...

Are there going to be any new drivers released at least compatible with the old 6x mcpcb with the integrated fet and thermal sensing resistor? Moreover, are you going to release an updated version of mcpcbs for the new drivers and should we be able to purchase them from a new eshop maybe?

Ps: If anyone is willingful enough and has an ld-b4 at 12amps available and sitting around, I am very much dying to contact them personally and buy it directly from them as it is of great importance to me.

Cheers

Old PCBs should be compatible with newer drivers. I don't have plans to make new MCPCBs with FET on them (mostly because it will not be needed).

Hi neven;
May be a stupid question but i got several ld4a drv in my mod box
And i dont know how to reconize a 6,9 or 12 amp one
Is there a way ?

There is a small smd resistor that sets the output range. I don’t know the values for each but I have changed the amps output on some charger boards. On those less resistance made the amps go up. Can you see if there is one resistor on each driver that is a different value?

Gonna check
Thanks

Look for 0402 resistor below uC chip; 75kOhm is 12Amp, 100kOhm 9Amp, 150kOhm 6Amp (or 3 Amp in case large shunt resistor is marked with "002" which is 2mOhm).

@ led4power,
is there an estimate date for shipping of the products bought in December?
I didn’t receive any e-mail with the shipping info, hence my question.
Thanks in advance :+1:

Thanks neven useful information

I was waiting for LD-4 parts to arrive, within couple of days.

Thank you for the reply :wink:
I will wait, no problem at all! :wink:
:beer:

Just wanted to let you know that my stuff has arrived :wink:
Haven’t tested it yet but I trust it is all well :wink:

Thanks again for your work and products :beer: :+1:

Hello L4P, I’m waiting for a delivery from post office, I’ve ordered some leds from you in December,now they seems stuck somewhere in my country,I will try to contact the post office,anything you can do for It? Will let you know how It ends up after some call :person_with_crown:

Other than tracking number, I don't have any more info about package,sorry.

What is the status on the store?

Still closed until further notice.

I don’t know what happened, but I hope that everything is going as well as it can be.

I’m just hoping that there will be a decent torch parts store in Europe again

Same here!

Is there any way to buy an LD-A4 driver?

Only if some member has spare ones and he's wiling to sell them.

What size and what amps are you after? (amps can be adjusted with a resistor swap. But they are tiny.)
