Hi,
I am new to the site. I am an amateur to fixing the circuit board. Now I have a LitepanelsMicro LED On-Camera Light, accidentally I connected the wrong power adapter and fried something. now the light turns on for a millisecond and turns off. looking at the board I fried a chip, I can only read half of what it says. It start With "LTQY 8144 " the 8 maybe 2 . can someone tell me what this may be ( fuse, step-down ect) please help

Thank you
Prince George

 

There are dozens of those panels out there and I can' find a good panel schematic or drawing, The part which cooked may have been a proprietary part as I had no luck with the numbers.

Hopefully someone else has a thought? I don't even have a good guess.

Three of the leads look like they are connected together. VReg or MOSFET. My money is on VReg.
