Palit Jetstream 1070 - SMD code question

[Prott]

Hi,
I got my hands on a 12 V / 5 V shorted Palit 1070. However few components got blown away during the short, including a 5V buck controller (marked SU2 on the photo).

The (supposed) 5V buck controller is marked W077 - so far it looks pin compatible with the standard RT7296F, however I can't find what exactly is this smd to double check with the datasheet.

Does anybody please know what is this W077 SMD and if I can safely exchange it for the usual RT7296?

Thank you.

UPDATE: It is a 1.8 V rail, not 5 V Good thing I started injecting 0.8 V.
