2.1 Connector Descriptions

J1, Pin 1 and 2 – VINPositive input voltage connection from the input supply for the EVM
J1, Pin 3 and 4 – S+/S–Input voltage sense connections, measure the input voltage at this point
J1, Pin 5 and 6 – GNDInput return connection from the input supply for the EVM
J2, Pin 1 and 2 – VOUTPositive output voltage connection
J2, Pin 3 and 4 – S+/S–Output voltage sense connections, measure the output voltage at this point
J2, Pin 5 and 6 – GNDOutput return connection
J3 – PG/GNDThe PG output appears on pin 1 of this header with a convenient ground on pin 2.
JP1 – ENEN pin 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 the output voltage. Alternatively, the jumper can be removed and a different voltage can be supplied on pin 1 to pull up the PG pin to a different level. This externally applied voltage must remain below 5.5 V.
