How many pins does it have? I can't see it properly in the image. Is it 4, 8 or 12 pins?

[–] sunkryst@discuss.tchncs.de 1 points 2 years ago (1 children)

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 :(

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
