J1, Pin 1 and 2 – VINPositive 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 – GNDInput return connection from the input supply for the EVM
J2, Pin 1 and 2 – VOUTOutput 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, 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 – SCLThe pin of this header should be connected to the SCL of the I²C
interface.
J3, Pin 10 – SDAThe pin of this header should be connected to the SDA of the I²C
interface.
JP1 – VID/PGVID/ PG pin jumper. Always 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 – 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.
