Looks like a PG-TDSON-8 packaged FET, pin 4 is the gate, 1-3 are the source, 5-8 are the drain. NIKO-Semiconductor, can't find the datasheet. Package aka PDFN 5x6 and others.

This is going difficult to replace: As you can see from the "left" side of the chip this kind of case is not only soldered at the pins but also on the bottom and there on a large area. This works as a heatsink. You'll need a hot air repair station, with a bit of luck and perseverance a hot air gun may do the job. It is also customary to pre-heat the pcb from the other side. Find a few tips in this discussion.

Thank you for the reply. I have a hot air rework station and a preheater. I feel confident if I can find a replacement chip, I should be able to repair the board.

Thanks again
