2.1 Input/Output Connector Descriptions

J1 – VINPositive input connection from the input supply for the EVM
J2 – S+/S-Input voltage sense connections. Measure the input voltage at this point.
J3 – GNDReturn connection from the input supply for the EVM
J4 – VOUTOutput voltage connection
J5 – S+/S-Output voltage sense connections. Measure the output voltage at this point.
J6 – GNDOutput return connection
J7 – PG/GNDThe PG output appears on pin 1 of this header with a convenient ground on pin 2.
J8 – SS/TR & GNDThe SS/TR input appears on pin 1 of this header with a convenient ground on pin 2.
JP1 – 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.
JP2 – PG Pullup VoltagePG pin pullup voltage jumper. Place the supplied jumper on JP2 to connect the PG pin pullup resistor to Vout. Alternatively, the jumper can be removed and a different voltage can be supplied on pin 2 to pull up the PG pin to a different level. This externally applied voltage should remain below 6 V.
