Demonstration board for MASTERGAN4 high power density half-bridge high voltage driver with two 650 V enhancement mode GaN HEMTs

The EVALMASTERGAN4 board is an easy to use and quick to adapt tool to evaluate the characteristics of MASTERGAN4 and to quickly create new topologies without the need of complete PCB design. The EVALMASTERGAN4 provides an on-board programmable inputs deadtime generator with a single VCC supply (typ. 6 V). An embedded Linear voltage regulator offers 3.3 V rail to supply low voltage logic circuit like microcontrollers or FPGA.
Some spare footprint is also included to customize the board to operate with final application. These customizations include: use of separate input signal or single PWM signal, use of external bootstrap diode, separate supply for VCC, PVCC or Vbo and also the use of low-side shunt resistor for peak current mode topologies.
All pins of the MASTERGAN4 are accessible.
The EVALMASTERGAN4 is 56 x 70 mm wide, FR-4 PCB resulting in an Rth(J-A) of 35°C/W, without forced airflow.
