MASTERGAN1 High Power Density Half-Bridge High Voltage Driver Demonstration Board with Two 650 V Enhancement Mode GaN HEMTs

EVALMASTERGAN1

Overview

The EVALMASTERGAN1 evaluation board is an easy-to-use and quickly adaptable tool for evaluating the performance of MASTERGAN1, allowing for the rapid creation of new topologies without the need for a complete PCB design.

The EVALMASTERGAN1 provides an on-board programmable input dead time generator powered by a single VCC supply (6 V typical). The embedded linear regulator provides the 3.3 V rail to power low-voltage logic circuits such as microcontrollers or FPGAs.
Some space is provided to allow the panels to be customized to the final application requirements. These customizations include: using separate input signals or a single PWM signal; using external bootstrap diodes; providing separate supplies for VCC, PVCC, or Vbo; and using low-side shunt resistors for peak current mode topologies.
All pins of MASTERGAN1 are also accessible.
EVALMASTERGAN1 is a 56 x 70 mm width FR-4 PCB with R _th(JA) of 35 °C/W and no forced convection.

Main features

Half-bridge demo board equipped with MASTERGAN1 and capable of 600 V
VCC input configured on screw connector or pin connection to power MASTERGAN1
Complete set of features to drive MASTERGAN1 with single or complementary drive signals
The embedded dead-time generator converts a single PWM signal into dual complementary LIN and HIN signals. The dead-time can be adjusted independently.
On-board 3.3 V regulator for powering external circuits (up to 50 mA)
Thermal resistance from junction to ambient is 35°C/W for evaluation of high power topologies
High frequency connector for MASTERGAN1 GL and GH pin monitoring
Leave room for low-side shunts, external bootstrap capacitors, and large capacitors for high voltage and high capacitance
Passed RoHS certification
