The synchronous push-pull converter was designed to operate at a switching frequency of 500 kHz. For space-grade converter designs, the benefits of GaN power devices over silicon counterparts are readily apparent at this switching frequency. Using Equation 7, the required RT resistor for the desired frequency can be determined as shown in Equation 24.
A standard resistor value of 205 kΩ is selected for the design.
