Another dead ASUS RT-AX88U

[mikochem]

Hello,

My ASUS RT-AX88U is completely dead and I would need help with IC Identification, My assumption is that the green circle circuitry is the same as the red one on my attached picture because the IC on the red side is so badly burnt that I can't read the reference anymore.

It appears to be a buck converter with reference "OQ=13T" any idea what this is ?

Thanks,

Michael

Possibly a richtek RT9074-25GFP ,heres the datasheet https://cdn.badcaps-static.com/pdfs/...67506c6b99.pdf

Parts with an = are usually made by richtek.

Thanks very much ! It looks like a match with "0q="

Also, could someone with the same router confirm that the burnt IC on the left side (U613) is the same as the one on the right side (U614) ?

I've been trying to source some Richtek RT9074-25GFP in MSOP8 package to no avail..
Seems like something with a fixed 2.5v output is difficult to find compared to the 3.3v equivalent.

Also I looked at Digikey and Mouser catalog to find something with the same pinout and so far no exact match from other vendors.
