Stmicroelectronics EVALMASTERGAN3 Demo Board provides a half-bridge topology reference design based on the masteran3 HV driver integrated GaN ehemt. The integrated power supply gan has R(DS(ON)) of 150 mm and 650V drain-source breakdown voltage. Integrated bootstrap diodes can quickly provide the high-end of embedded gate drivers.

     Stmicroelectronics' EVALMASTERGAN3 demo board comes pre-installed with the MASTERGAN3 driver in the QFN package. The demo board also includes an onboard programmable input dead-time generator with a single V(CC) power supply. Embedded linear regulators provide a 3.3V rail to provide low-voltage logic circuits like microcontrollers or FPGas.

     Included are spare takeaways to make custom boards for final applications such as separate input signals or single PWM signals, use of an optional external guide diode, separate power supply V(CC), P(VCC), or V(bo), and use of low side shunt resistors for peak current mode topologies.
