What's this please? (Component Advice)

[diefenbaker]

hi all, new to the forum so hope I'm in the right place.

I have an intel NUC that has died and I believe this regulator needs replacing. Possibly more components of course but starting with this for now.

Can anyone please help me identify the component and point me in the direction of where I might buy a replacement?
In this image that has the markings EBA7PA. Ive added an image of the burnt one too.

For context it is close to where the PSU plugs into the NUC and the PSU provides 19v/3.42A.

Thanks Gamalot. Is it worth me powering up the working nuc and trying to measure the output of the component?
My thinking is I would be able to confirm the inputs/outputs match the spec on the parts you've highlighted.

Yes, of course, please do that. Carefully measure the voltages on all pins. Use external test points, if appropriate, to avoid damage due to slips with the probe.
