Help identifying buck controller please

(1/1)

ManCave:
Hi, I've taken apart friends galaxy projector that stopped working. Could you please help identifying the buck controller from whatever is left of the original? It's used to step down 5V to drive the projector diode. It's likely few hundred mA...

I'd appreciate any help.
Thanks!
