2.1.1 Connector Descriptions

J1, Pin 1 and 2 – VIN Positive 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 – GND Input return connection from the input supply for the EVM.
J2, Pin 1 and 2 – VOUT Positive 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 – GND Output return connection.
JP3 – PG/GND The PG output appears on pin 1 of this header with a convenient ground on pin 2.
JP1 – EN EN 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 Voltage PG 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 5.5V.
