9.2.2.7 Main Switching FETs
In the push-pull topology, the switching devices on the primary side will see a voltage that is equal to twice that
of the input when the devices are off. As such, the GaN FETs selected should have a voltage rating that 3 times
higher than the input voltage. The voltage rating for the GaN FETs was conservatively chosen for the primary
