2.1.1 Input and Output Connector Descriptions

Table 2-1 Input and Output Connectors
Input and OutputDescription
Jx1, Pin 1 and 2 – VINPositive input connection from the input supply for the EVM.
Jx1, Pin 3 and 4 – S+/S-Input voltage sense connections. Measure the input voltage at this point.
Jx1, Pin 5 and 6 – GNDInput return connection from the input supply for the EVM.
Jx2, Pin 1 and 2 – VOUTOutput voltage connection.
Jx2, Pin 3 and 4 – S+/S-Output voltage sense connections. Measure the output voltage at this point.
Jx2, Pin 5 and 6 – GNDOutput return connection.
JPx1 – ENEN pin input jumper. Place the supplied jumper across ON and EN to turn on the IC. Place the jumper across OFF and EN to turn off the IC.
Note:

To achieve a different output voltage, disconnect the power supply of the EVM. Replace the R11/R21/R31 accordingly (refer to the TPSM82843 1.8V to 5.5V, 600mA, 275nA IQ, Step-Down Converter with Integrated Inductor in QFN Package data sheet), then power up the device again.
