2.1.1 Proper Board Connection

Figure 3-2 depicts the typical evaluation setup. The source power is connected to the J1 (VIN) and the J3 (GND). The load is connected to the J2 (VOUT) and the J4 (GND). Be sure to choose the correct connector and wire size. The input and output voltage must be monitored directly at the terminals of the board. The voltage drop across the connection wires causes inaccurate measurements.
