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 – 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.
