My motherboard (Gigabyte b450) died after a power outage. I found out that an SMD 5-pin IC with the code VA8qE was burned. I tried to identify it myself, with no luck.

I searched for the code online, but no result, even on pages like:

Any idea what it is?

    \$\begingroup\$ UPDATE: with actual picture of the component, seem that 5 pic give voltage to the ITE chip. there is a exact chip near the chipset, i removed that one and replaced the burned, now the mobo turn on, but no video, so i sill need to replace it. \$\endgroup\$

  • \$\begingroup\$ Could it be one of the "VAB" components listed at smd.yooneed.one/code5641.html ? Does the working one have an output of 1.1 V? \$\endgroup\$

I think it says "VAB", in which case it's probably a S-1135 Series voltage regulator.

More specifically the "S-1135C11-M5T1y", according to the datasheet.

Doing some reading with the multimer on the same 5 pin not burned VA8qE next to the chipset, it looks like it a voltage regulator, 5 V input 3.3 V output. I found (different code) in an old motherboard I had around, measure, and the MOBO is live again, booted to BIOS so far.
