The LTspice simulation indicates that the driver current has a peak value of 1.3 A, an rms (root-mean-square) value of 94.602 mA, and an average value of 14.876 mA. The driver power supply voltage is 12 V dc. What is the average gate driver power consumption?

(1.3 A)(12 V) = 15.60 W
(94.602 mA)(12 V) = 1.135 W
(14.876 mA)(12 V) = 0.1785 W
