Help identifying burnt out chips on ssd (probably dc-dc?)

[eugene_black]

Hi

I have three apacer panther SSDs and two of them have burnt out components which I struggle to identify. Here are pictures of the component from all three SSDs. They have different marking but have the same placement and function so I assume they are interchangeable.

Thanks

Do you have also some info about the diode that stands on the power line? It is pretty small so it is a bit confusing for me

Maybe this?

Very disorganised, with a lot of duplication ...
