2.1 Input/Output Connector Descriptions

    J1, Pin 1 and 2 – VIN Positive input 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 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
    J3, Pin 5 – VBUS The VBUS pin of this header is used to bias the SCL and SDA nodes of I²C interface via a resistor.
    J3, Pin 6 – GND The GND pin of this header is used to connect the grounds of the IC and the I²C interface.
    J3, Pin 9 – SCL The pin of this header should be connected to the SCL of the I²C interface.
    J3, Pin 10 – SDA The pin of this header should be connected to the SDA of the I²C interface.
    JP1 – VID/PG VID/ PG pin jumper. Place the jumper across VID/ PG and LOW pins before start-up. This sets the output voltage and device address. After startup, VOUT reflects the value set on VOUT Register 1 if the jumper is placed across VID/ PG and LOW pins. VOUT follows the value set on VOUT Register 2 if the jumper is placed across VID/ PG and HIGH pins.
    JP2 – EN EN pin input jumper. Place the jumper across ON and EN to turn on the IC. Place the jumper across OFF and EN to turn off the IC.
