Recommendation of Gate Driver Power - GM3 Module

shawn

Customer is evaluating CAB006M12GM3 and its gate driver, as the target fsw is 100kHz(hard-switching), according to the gate driver power dissipation fomula: P=Qg*fsw*(Vdd-Vss), the required Power of gate driver is 708nC*100kHz*[15V-(-3V)]=1.3W.

So if considering a reasonable margin, what's the power we should recommend cutomer to design? And if there is any margin design guideline we can follow?

Thanks!
