2.1.1 Connector Descriptions

J1, Pin 1 and 2 – VINPositive 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 – GNDInput return connection from the input supply for the EVM.
J2, Pin 1 and 2 – VOUTPositive 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 – GNDOutput return connection.
JP1 – ENEN 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 – MODE/SYNCMODE/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.
JP3 – PGThe PG output appears on pin 1 of this header with a convenient ground on pin 2.
JP4PG pullup resistor jumper.
