Hi!
I want to ask some question about it :
1. Is is ok to use the kind of Mosfet which attached with a diode in a basic buck converter?
2. I have read some basic calculations of buck converter, they recommend me a minimun value of inductance for a specific converter. So Is it alright to use a higher inductance value ?
3. Is this the formula to calculate switching frequency ( I'm using UC3843) ?
f=1/(2*pi*RC)
4. While searching the net, I have noticed in some circuits, there is a registor connected between the output pin of the controller and the gate of the mosfet, I want to ask what does it do, Is it necessary
That's all my question. Thanks for reply.
