What part is this marked .AC ?

[Shimra]

I know this is a LED driver, as it drives UV LED's but I need to find equivalent, or datasheet of this part.
Anybody has an idea?

Nothing in the SMD marking database under AC for either a LED driver or current controller.

The SMD components marking codes database - Starting with 'AC'

Did you try this decoder? https://smd.yooneed.one/

Thank you all, but neither of these are giving me the part I am looking for. So hard to find.

Yes, it is very difficult to find out what an IC is with so little information.

Unfortunately SM parts are often unlabelled, or use an in-house code, meaningless to anyone else. You need to get the details off the service manual, which is pretty certainly not available to you (or anyone else), or you're stuffed.

It doesn't help that's it's most likely a cheap Chinese device, and will use the cheapest chip they could find, regardless of availability.

Thanks all for helping, for now I am stuck and will put project aside and hope in next few weeks to pick it up again to do another deep search. I am getting more of these equipment to repair so it is becoming a must for me trace back this part

Are you sure it drives the UV ones?

Looking at the PCB, it appears to connect to the white body LED, not the odd looking UV one next to it?
It may be just a surface mount transistor.

Better overall views of the PCB track showing where they go could help?
