2.1.1 Connector Descriptions

J1, Pin 1 and 2 – VINInput return 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 – GNDPositive input voltage connection from the input supply for the EVM.
J2, Pin 1 and 2 – VOUTOutput return connection.
J2, Pin 3 and 4 – S+/S–Output voltage sense connections. Measure the output voltage at this point.
J2, Pin 5 and 6 – GNDPositive output voltage 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 – MODEMODE pin jumper. Place the supplied jumper across VIN and MODE to force the device in fixed frequency PWM operation at all load currents. Place the jumper across MODE and GND to enable power save mode.
J3 – PG/GNDThe PG output appears on pin 1 of this header with a convenient ground on pin 2.
