I am trying to understand MOSFETs. A tutorial I read seemed clear except it pretty implied that there was little or no current flowing through the gate—that it was essentially voltage driven.
Yet when I read threads about MOSFETs I see “beefy gate driver” and “is there sufficient gate current?”
Was the tutorial (not yours—yours has not been finished yet) oversimplifying?
Related to this, though I don't know how, is the fact that the data sheets I have seen seem to be using a duty cycle of 0.5% !! That seems to me to be unusably low.
Help is appreciated.
