Hello Sonsivri,

Thought some people might find this useful.  I am working on a project that must switch a MOSFET at very high speed.  The power budget for the control circuitry is very very small, so the power required to drive the mosfet (gate) is actually a concern.

I did a little searching and found a supertex application note that describes exactly how to (accuratly) calculate the total power and average current required to switch a mosfet at a frequency.

Hope this helps someone...
