• MAXM15067EVKIT# Equipment Setup and Test Procedure The EV kit is fully assembled and tested. Follow the steps below to verify the board operation. Caution: Do not turn on power supply until all connections are completed. 1) Set the power supply at a voltage between 4.5V and 60V. Then, disable the power supply. 2) Connect the positive terminal of the power supply to the VIN PCB pad and the negative terminal to the nearest GND PCB pad. Connect the positive termi - nal of the 300mA load to the VOUT PCB pad and the negative terminal to the nearest GND PCB pad. 3) Connect the DVM (DMM in voltage-measurement mode) across the VOUT PCB pad and the nearest GND PCB pad. 4) Verify that shunt is not installed on jumper J1 (see Table 1 for details). 5) Turn on the DC power supply. 6) Enable the load. 7) Verify that the DVM displays 6.3V.
