Figure 4 Evaluation board with daughter card and DUTs
The switches are driven by compact driver ICs from the respective daughter card. The two drivers are
independently controlled by PWM signals on the connectors X103 for the high-side and X104 for the low-side
PWM. Additionally, this evaluation board supports an external XMC4800 controller board to supply double-pulse
or constant PWM signals enabling wireless connectivity. The process for using and connecting the XMC4800
controller to the evaluation board is provided in the user guide for the EVAL_XMC4800PSOC6M5 board [4].
A heating feature is implemented on the board to analyze switching losses at high temperatures. The power
resistor, RPOW, and the thermistor, RNTC, can be used to adjust and monitor the heatsink temperature.
The gate voltage, the drain-source voltage, and the drain current can be measured using an oscilloscope to
investigate the device's switching behavior. Measuring the voltage is simple, but measuring the current is more
challenging, especially when there are high current slopes. A surface-mounted device shunt resistor is provided
on the evaluation board to make measuring the current easier.
