3.1 Connector Descriptions

MH1 - VINPositive input voltage connection from the input supply for the EVM
J1-1 – VINsense, J1-2 – GNDsenseInput voltage sense connections, measure the input voltage at this point.
MH2 – GNDInput return connection from the input supply for the EVM
MH3 – VOUTPositive output voltage connection
J8-1 – VOUTsense, J8-2 - GNDsenseOutput voltage sense connections, measure the output voltage at this point.
MH4 – GNDOutput return connection
J3 – 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.
J4 – 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.
J5 – PGThe PG output appears on pin 1 of this header with a convenient ground on pin 2.
J7 – SYNC_OUTAt the SYNC_OUT output, the switching frequency is provided at pin 1 with a convenient ground on pin 2.
J6 – I2CI2C connection configured for being used with the USB2ANY interface.
