Description

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.
