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…
thanks!
Dave
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.
