8.2.1 Design Requirements

When designing a synchronous buck converter application that incorporates the LMG1205 gate driver and GaN power FETs, some design considerations must be evaluated first to make the most appropriate selection. Among these considerations are the input voltages, passive components, operating frequency, and controller selection. Table 8-1 shows some sample values for a typical application. See Section 9, Section 10, and Section 8.2.2.3 for other key design considerations for the LMG1205.
