2.1 Input/Output Connector Descriptions

J1 – VINPositive input connection from the input supply for the EVM
J2 – S+/S–Input voltage sense connections. Measure the input voltage at this point.
J3 – GNDReturn connection from the input supply for the EVM
J4 – VOUTOutput voltage connection
J5 – S+/S–Output voltage sense connections. Measure the output voltage at this point.
J6 – GNDOutput return connection
J7 – PG/GNDThe PG output appears on pin 1 of this header with a convenient ground on pin 2
J8 – SS/GNDThe SS pin voltage appears on pin 2 of this header with a convenient ground on pin 1
J9 – Vdd/GNDAn externally applied voltage must be applied on pin 2 of this header with a convenient ground on pin 1. This voltage must remain between 0.8 V and 6 V. This voltage level sets the logic high level for the VID0, VID1, and LPM pins as well as the PG pin pull-up voltage.
JP1 – ENEN pin input 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 – VID0VID0 pin input jumper. Place the supplied jumper across HIGH and VID0 to set the VID0 pin high. Place the jumper across LOW and VID0 to set the VID0 pin low.
JP3 – VID1VID1 pin input jumper. Place the supplied jumper across HIGH and VID1 to set the VID1 pin high. Place the jumper across LOW and VID1 to set the VID1 pin low.
JP4 – LPMLPM pin input jumper. Place the supplied jumper across HIGH and LPM to disable the low power mode. Place the jumper across LOW and LPM to enable the low power mode.
JP5 – PG Pullup VoltagePG pin pullup voltage jumper. Place the supplied jumper on JP5 to connect the PG pin pullup resistor to Vdd. Alternatively, the jumper can be removed and a different voltage can be supplied on pin 1 to pull up the PG pin to a different level. This externally applied voltage must remain below 7 V.
