In many circuit, like buck converters, MOSFET used in high side for switching, I've came across the term that Gate voltage with respect to ground must be greater than source voltage by +8V.
For example, Vs = 60V Vg = 68V (should be).
We generally implement a bootstrap circuit to achieve this higher voltage.
But, ideally as datasheet of any general MOSFET says, Gate voltage should be VGS = 20V. If I consider this MOSFET.
So, if VGS should be 20V then how MOSFET will work on Vg = 65V?
NOTE: Consider Gate is triggered at 13.5V PWM according to this datasheet.
