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
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.
JP3 – PG/GND The PG output appears on pin 1 of this header with a convenient ground on pin 2.
JP4 – GND Additional ground connection. Can be left floating if not used.
JP5 – SW Test point This test point is the SW node test point. Use only if needed. Can be left floating.
