The MAX5389 EV kit is fully assembled and tested.
Follow the steps below to verify board operation:
1) Verify that shunts are configured in the EV kit default
2) Apply a 5V power source across the VIN and GND
3) Connect the multimeters to measure voltage across
state for proper startup operation (see Table 1).
