J1, Pin 1, 2 and 3– VINPositive input connection from the input supply for the EVM
J1, Pin 4, 5 and 6 – GNDInput return connection from the input supply for the EVM
J2, Pin 1 ,2 and 3– VOUTOutput voltage connection
J2, Pin 4, 5 and 6 – GNDOutput 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 – GNDThe GND pin of this header is used to connect the grounds of the IC and the I²C interface.
J3, Pin 9 – SCLConnect the pin of this header to the SCL of the I²C interface.
J3, Pin 10 – SDAConnect the pin of this header to the SDA of the I²C interface.
JP1 – VID/PGVID/ PG pin jumper. Place the jumper across VID/ PG and LOW pins before start-up. This sets the
output voltage and device address. After start-up, 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 – ENEN 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.
