How many pins does it have? I can't see it properly in the image. Is it 4, 8 or 12 pins?
i just checked with the person who checked my computer, 12 pins
unfortunately i neither could find anything. richtek has some weird packages like this:
or like this:
so i poked around their homepage. but could not find anything with that pinning. also FMM marking is not in their marking reference :(
thank you so much anyways 🙏 i’m still looking for the schematic
looks very similar to that: https://www.ti.com/product/TPS566235
diodes uses packages like this one: https://www.diodes.com/assets/Package-Files/V-QFN2030-12-Type-HE.pdf but cant find FMM marking there ...
it could be worth a try to contact diodes and ask which components use or have used in the past V-QFN2030-12 (Type HE) package
thank you so much for your help!! i will contact them. my searching for the gateway schematic gave no results :( even in chinese google...
