WebThis is the easiest spec to use to calculate the maximum “theoretical” switching speed of the MOSFET. Calculating Power and Heat Dissipation. An important – and simple – calculation to make is to see how much power the MOSFET will dissipate at a given load. The max load we have is at a stall of 25A, with a max Rds(on) of 1m4. Webenergy required to charge the MOSFET gate. That is, the Q G(TOT) at the gate voltage of the circuit. These are both turn-on and turn-off gate losses. Most of the power is in the MOSFET gate driver. Gate-drive losses are frequency dependent and are also a func-tion of the gate capacitance of the MOSFETs. When
