9.2.1 Design Requirements

The example provided is to demonstrate the usage of TPS7H6005 in a high voltage synchronous buck converter. The design example is intended to detail component selection and configuration related to the TPS7H6005. For this particular application, the gate driver is operating in PWM mode.

Table 9-1 Design Parameters
PARAMETERVALUE
Power stage input supply voltage100V
Output voltage28V
Output current10A
Switching frequency500kHz
Gate driver input voltage12V
Duty cycle28% nominal, ~35% maximum
Inductor15μH
GaN FETEPC2307 (evaluation only)
Operating modePWM

Note that the selected GaN FET is for laboratory evaluation fo the driver. TI recommends selecting a GaN FET that satisfies both the electrical and radiation requirements of the design.
