# GAN FET gate current requirement

I'm looking for advice in making sure the FET driver I've chosen is capable of driving the FETs I've chosen with turn on time as low as possible.

I'm going to use the LMG1210 and EPC2020 with 12V rails switching at $$\500kHz\$$. The datasheet says the gate charge ($$\Q_g\$$) is $$\16nC\$$ typ. The peak current of the LMG1210 is $$\3A\$$. Am I correct in saying the minimum turn on time of this FET can be calculated using:

$$\T_{on} = \frac{Q_g}{I_g} = \frac{16nC}{3} = 5.3nS\$$
