Help with Component identification.

[Spider1211]

Hi guys, grateful if anyone can help with identifying part number of the following IC.

Laptop: HP pavilion X360 convertible
Motherboard: Bucks_NVDIS_MB; 16871-1; 448.0BZ03.0011

IC marking: BAC71H
Location on board: PU4502

I can't seem to find schematic for this motherboard but reversing the tracks I am fairly confident its the IC responsible to produce 5V.

Additionally if anyone can also provide part number for the following component (same motherboard);

IC marking: AWV7EE
Location: PU4501

Thank you!!! Pin mapping looks to be same. Any idea about the other IC? Most likely it'll be the 3.3V.

Attached is the connection diagram of the SY8288CRAC if anyone needs it.

It seems the AWV7EE could be SY8286BRAC. Grateful if anyone can confirm same.

1) how many pins?
2) U4001 on which logic board?
3) can you post a clear picture of the part?


"T109" will likely be the SMD marking to identify the component.
"5016" is likely the datecode where this marking means 50th week of 2016.

Perhaps the attached by Ricoh ?

Does your device match the package as per attached?
