Mikrotik 750up board schematic

Hi everyone!

I have bunch of Mikrotik 750up routers. Some of them burned because of voltage issues. I believe if i could change this element on board, i could make them work. But i did not find anywhere any information about their schematics. Would anyone help me about recognize this element?

Thanks
