Hi,
I need average current.
Yes, i can understand in forum, we can't give all the information.
But how I am calculating is--
Ig(avg)=Qg/Tsw(on)
Tsw(on)= on time of MOSFET(for that we need to consider duty cycle)
I am taking 2% duty cycle.
Tsw(on)= switching frequency*0.02
And one more...
I am calculating required gate current to turn on my MOSFET-BUK9M42-60E.
I am driving this MOSFET directly from microcontroller. It is logic level MOSFET.
I have these data from datasheet of MOSFET.
Vgs(th)=2.1V(max)
Vgs(supply from microcontroller)= 5v
Vds(battery voltage)=15v
Qg(total)=8.3 nC...
