Switch Lite Fan chip Part Number?

Has anyone identified the 3x3 BGA buck chip used to power the fan in the lite (marked in attached). I believe it is the same chip as the original switch. I have a couple that are bad and no luck with donor boards - this chip is far too small to re-ball for me! Tried to figure it out from Mouser catalog and PCB layout but there are hundreds of these…

On my donor board it’s marked AJZ and it is a MAX8969EWL50+T. They come preballed at $1.78 each on digikey. These also power the joycons/fan rail on the switch and switch OLED.

THANKS! Even better, that lets me get the data sheet so I can figure out which pin is causing it to run full speed while the switch is turned off.
