Alright i understand how a diode placed across the mosfet protects it frm reverse currents, but how does a bypass cap at the output of the mosfet achieve the same thing?
Dont mind explaining it to me?
Thank you!
Alright. Now that I've read a bit more on SMPS, specifically the boost types, am I right to say that a flywheel diode is not needed in my circuit?
When the mosfet switches off, the induced current flows toward the smps and not back to the mosfet because the inductor is placed after the...
I shouldn't put the catch diode across the inductor?
May I know why?
Im concerned that when the supply is cut, the back current induced would damage my mosfet. Or will it not?
Many thanks again.
Hi all. This is my first post here. Really hope someone can help :)
Im facing some problem regarding the design of my little switch mode boost regulator. It uses the max631, which has a built it catch diode.
The input voltage to the max631 comes from a logic controlled p channel mosfet...
