Help identify QFN11 converter

DC-DC Power Converters
1

Hello. I’m struggling with identifying a component in a circuit.

It’s a buck converter in qfn-11 package, but I can’t find it by it’s top marking (GCR-811).

I tried to search for GC*, and found a similar converter - MP2329C which is HB*. Problem that is mine working with 3.3V input, and has 1.0uH inductor instead of 1.5uH.

I don’t know if that information will help at all, but it’s getting Vin from NB680 converter, and max Vin in circuit (which is motherboard for OPS PC) is 19V.

converter

Thanks in advance!

UPDATE: I guess it’s a NB591GG-Z, but I can’t find datasheet anywhere.
