PU401, MOTHERBOARD DA0G3DMBCE0 REV:E

[klynstronic]

Hi Hi.
Can you help me? The boardview of the DA0G3DMBCE0 REV:E motherboard says that the PU401 IC is a MP86903C...however this is a TQFN21. The PU401 is a TQFN13 and the MP86901-AGQT-Z IC is TQFN13.
Am I correct? Or is it a different IC?
I would appreciate an answer.
Regards.

Do you have the original part from this motherboard? Post clear pics of the PCB where this part was originally mounted.

My bv file also reports the part to be MP86903C. If you have the original part, post top and bottom side clear pics of the part for a review.

Hi.
Thank you for your reply.
The chip is quite damaged although some letters and numbers can be seen. I think it indicates AMVJ 944.

Good catch! The boardview is wrong.

The part on your board is indeed MP86901-AGQT-Z. The topside markings on the replacement should also bear the same first 3 markings of ‘AMV’.

No datasheet available but the chip is in the Clevo NL50CU NL51CU Service manual schematic https://www.badcaps.net/forum/troubl...nual-schematic ,and in the Monolithic Power Solutions for Powering
