Hey guys,
I ordered this driver and it’s said it has some heat issures. I would like to see if I could improve the efficiency or maybe make it 800mA, so that it doesn’t waste that much energy and stays a bit cooler.
I tried to figure out wich components are used for the boostcircuit, to get their datasheets and have a look at their specifications.
These are pics from DX:
I figured, that the 7136 and Q2 might be a linear regulator for V_in>V_led.
So IC1 and Q1 should be the boosting parts. I searched now for quiet a while, but couldn’t find any datasheets or at least the full name of the IC (7N11 does not seem to be the whole name).
Does anybody know this driver and could tell me its full name or even post where I can find the datasheet?
Greets,
flo
