Hello! Does anyone know how to limit (set) current on hx-1341 driver? (I’m looking for the name of the ic driver also…)
pics please
That model sounds familiar, but all their model numbers sound the same to me. Yeah, a good pic of the top and bottom is much more likely to get you some help.

they scraped all the ic tops.
Thanks!
…you have to take a picture of the coil side with the coil and capacitor bend a bit up because underneath them are probably the resistors….
nothing similar to a shunt…
hall sensor? too expensive I think…
Interesting driver. It looks like the source pin is connected directly to ground with no resistors in between. The gate appears to be feed by those 2 parallel 3 pinned jobbers.
I don't have enough electronics knowledge to be of assistance on this guy. Do you know what light it came out of?
The resistor on the front left “edge” looks like a small one, R043…
Oh, that pic looks familar. I think OL had a thread on it and it was discovered to be a boost driver. I'll see if I can find it.
EDIT: Here it is. Different driver, but very similar looking circuit. Maybe you can find an answer towards the end of it.
EDIT2: Werner's guess looks right to me too. But if this is a boost driver, you probably won't have much upside potential in this driver.
