2.2 Header Information

J1 – VIN/GNDInstalled on TPSM82816PEVM-062 only.

Input and return connections from the input supply for the EVM. This connector supports currents over 3A and accepts up to 16AWG wire.

J2 – VOUT/GNDInstalled on TPSM82816PEVM-062 only.Output and return connections from the EVM to the load. This connector supports currents over 3A and accepts up to 16AWG wire.
J3 – PG/GNDThe PG output appears on pin 1 of this header with ground on pin 2.

J4 – SS/TR and GND

The SS/TR signal appears on pin 2 of this header with ground on pin 1. A tracking signal can be applied on the SS/TR pin.
J5, Pin 1 and 2 – VINPositive input connection from the input supply for the EVM

Do not use for currents above 3A.

J5, Pin 3 and 4 – S+/S–Input voltage sense connections. Measure the input voltage at this point.
J5, Pin 5 and 6 – GNDInput return connection from the input supply for the EVM.

Do not use for currents above 3A.

J6, Pin 1 and 2 – VOUTOutput voltage connection

Do not use for currents above 3A.

J6, Pin 3 and 4 – S+/S–Output voltage sense connections. Measure the output voltage at this point.
J6, Pin 5 and 6 – GNDOutput return connection

Do not use for currents above 3A.
