Hello,
What is the input capacitance of the GaN FET? Datasheet doesn't specify this parameter. I want to calculate total gate driver loss at different frequencies.
Thank you,
Shaury

Hi Shaury,
We are checking this with our validation team at the moment. We will update you once we have this data available.

Hi Shaury,
For the gate drive loss calculation please use a total gate charge Qg of 43 nC, and a Vg of -14 V.
You can then use the total gate drive loss equation: P_gate = Vg*Qg*f_sw.
Best Regards,
John
