2.1.1 Connector Descriptions

MH1 – VIN Positive input voltage connection from the input supply for the EVM
J1-1, J1-3 – VINsense, J1-2, J2-4 - GNDsense Input voltage sense connections, measure the input voltage at this point
MH2 – GND Input return connection from the input supply for the EVM
MH3 – VOUT Positive output voltage connection
J2-1, J2-2 – VOUTsense, J2-3, J2-4 - GNDsense Output voltage sense connections, measure the output voltage at this point
MH4 – GND Output return connection
JMP1-1, JMP1-3 – EN EN pin jumper. Place the supplied jumper across VIN (JMP1-2) and EN to turn on the IC. Place the jumper across GND (JMP1-4) and EN to turn off the IC.
JMP1-5, JMP1-7 – MODE/SYNC MODE/SYNC pin jumper. Place the supplied jumper across VIN (JMP1-6) and MODE/SYNC to force the device in fixed frequency PWM operation at all load currents. Place the jumper across MODE/SYNC and GND (JMP1-8) to enable power save mode. Connect a clock signal to MODE/SYNC referenced to GND to synchronize the switching frequency to the clock signal.
JMP2-2 – PG The PG output appears on pin 2 of this header with a convenient ground on pin 4.
JMP2-6, JMP2-8 – SYNC_OUT At the SYNC_OUT output the switching frequency is provided at pin 6 and 8 with a convenient ground on pin 5 and 7.
J5 – I2C I2C connection configured for being used with the USB2ANY interface.
