WebAug 21, 2024 · Your total loss is Vdd.Idd . On each turn-on cycle, a charge Qg is consumed from Vdd and delivered to the FET's gate. This (resistive via a FET) charging is precisely 50 % efficient -- half the energy consumed from Vdd is dissipated in the driver, and the other ½ is stored in the gate capacitance. WebQg is the total gate charge. If Qg is larger, it needs a stronger driver and more charge. Figure 2 shows the relationship between Qg and Vgs voltage and how much charge the gate of MOSFET requires at different gate voltage. For example, if VGS wants to get 5 V, the gate of MOSFET need to be charged about 4 nc. WebIt takes a certain amount of time to fully charge a capacitor. The same is true of the capacitance of a MOSFET gate. The most useful specification on a MOSFET datasheet for this is the “Total Gate Charge.” “Injecting” this amount of charge into the gate of a MOSFET fully turns it on. craftsman inflator
