Quick Start 4) Connect the power supply between the VIN and Required Equipment GND PCB pads on the EV kit. MAX16946 EV kit 5) Connect the load between the REG OUT and GND 18V, 200mA DC power supply PCB pads on the EV kit. Load 6) Connect the first voltmeter between the REG OUT Two voltmeters and GND PCB pads on the EV kit. 7) Connect the second voltmeter between the AOUT Procedure and GND PCB pads on the EV kit. The EV kit is fully assembled and tested. Follow the steps below to verify board operation. Caution: Do not turn 8) Enable the power supply and the load. on power supply until all connections are completed. 9) Verify that the first voltmeter displays 5V. 1) Verify that all jumpers are in their default position, as 10) Verify that the second voltmeter displays 790mV. shown in Table 1. 2) Adjust the power supply to 10V. 2 Evaluates: MAX16946
