Toroids and MOSFETs and firmware, oh my! (aka:'Tiny13+N-FET=???')

ok…thank you for help…I will buy AOD510…
what about gate resistor for AOD510? is 10 Ohm ok?

thank you

I have never tried an AOD510 on that driver with the stock MCU. If it works without a gate resistor, it does not need one. If it does not work without one, it does need one. You are the only one who can lay hands on that particular combination of parts, you will have to figure out what it needs.

I like to buy 70N02 but I cant find it anywere.is there another alternative fet?

Alpha & Omega AOD510. http://www.aosmd.com/pdfs/datasheet/AOD510.pdf

I see that all the two fet is dificoult to find it

There should not be any trouble finding the AOD510 somewhere in EU, they are still in production. The Vishay 70N02 is discontinued, that one you are not likely to find in stock anywhere.

what do you think?
NIKOS P70N02LDG TO-252
Vdss=25V
Rds(on)=5mOhm
Id=75A

is this OK??
