Vnoo3 is the drive voltage, and Ig is the gate current. What I am wondering is:
1) How to calculate the peak Ig on the rising edge of the pulsed gate voltage? For instance, using the spice image below. It's a 400kHz "square" wave with a 45% duty cycle.
2) How to use the datasheet to find out what drive current is necessary to be able to drive the MOSFET at a certain frequency? Please provide a real example. I understand the gate-charge vs vgs curve, and how the miller capacitance effects the charging of the gate capacitance, but I am not able to connect the dots to do what my question is asking.
Please let me know if you need more information.
