Somewhat bizarrely, this appears to be a custom part number used by Samsung for a TI DC/DC converter: SN1208017DDAR.

It's mentioned in this PCN, so it's likely to be the same as one of the other part numbers mentioned in that. The few I checked are variants on "4.5V to 18V Input, Synchronous Step-Down Converter".

Pinouts don't match though, so it seems the part is available in different pinouts. You might be able to match the Samsung part to one of the pinouts. Or you can get the one with the Samsung part number from some Samsung spare parts vendors...
