Hardware

2.2 EVM Setup

Use the VINS+ and VINS– test points along with the VOUT1S+, VOUT1S–, VOUT2S+, VOUT2S–test points
located near the power terminal blocks as voltage monitoring points where voltmeters are connected to measure
the input and output voltages, respectively. Do not use these sense terminals as the input supply or output
load connection points. The PCB traces connected to these sense terminals are not designed to support high
currents. Before applying power to the EVM, make sure that the jumpers are present and properly positioned
for the intended output voltage. Always remove input power before changing the jumper settings. Always use
caution when touching any circuits that can be live or energized.
Extended operation at high output current can raise component temperatures above 55°C. To avoid
risk of a burn injury, do not touch the components until cooled sufficiently after disconnecting power.
Wire gauge for the input power supply and the output electric load must be 9 AWG minimum and
no longer than 1 foot. Please tighten the input and output terminal screws to minimize contact
resistance.
2.2.1 Input Connections
• Connect voltmeter1 at VINS+ and VINS– .
• Connect ammeter1 to VIN+.
• Prior to connecting the power supply, set the current limit of the power supply to 0.3A maximum and make
sure the initial output voltage is set to 0V. Connect to the VIN- and the ammeter1 as shown in

2.2.2 Output Connections

• Connect voltmeter at VOUTS+ and VOUTS– sense points to measure the output voltage.
• Connect load to the VOUT+ and VOUT– connections as shown in
resistance mode or constant-current mode at 0A before applying input voltage.
