So, I had time to test the part on a working board. It seems to me, that it is a DC DC converter. MP2359.

The connections and layout is similar to the datasheet. Only r1 and r2 are different to the output voltage. According datasheet I need for 5v output r1 49.9kohm,r2 9,53kohm. But I have r1 8 kOhm, r2 1.39 kOhm. See attached pictures. Maybe someone can assist.
