2.1 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
J3 – 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.
J4 – MODE/SYNC MODE/SYNC pin jumper. Place the supplied jumper across VIN and MODE/SYNC to force the device in fixed frequency PWM operation at all load currents. Place the jumper across MODE/SYNC and GND to enable power save mode. Connect a clock signal to MODE/SYNC referenced to GND to synchronize the switching frequency to the clock signal.
J5 – PG The PG output appears on pin 1 of this header with a convenient ground on pin 2.
J6 – SS/TR SS/TR input, a voltage connected on pin 1 of this header referenced to GND on pin 2 can be used to control the output voltage (tracking).
