This is the enable input for the device. Place a shunt across the ON and EN pins of J3 to enable the
integrated circuit (IC). Place a shunt across the OFF and EN pins of J3 to disable the IC. A shunt must be
installed on J3 in either ON or OFF positions and EN should not be left unconnected.

This jumper allows the user to program the output voltage. Place a shunt across the H and Vctrl pins of J4
to set the output to the high default value of 3.09 V. Place a shunt across the L and Vctrl pins of J4 to the
output to the low default value of 1.3 V. Remove the shunt and connect a voltage source to the Vctrl pin of
J4 to program a voltage between 1.3 V and 3.09 V. The output tracks the voltage at the Vctrl with a gain
of 2.5. See the Dynamic Output Voltage Control V

Connect the positive input power supply to the Vin pins on J1. Connect the input power return (ground) to
the GND pins on J1. The TPS62700EVM-264 has a maximum input voltage of 6 V. The recommended
maximum operating input voltage is 5.5 V.

Connect the desired load between the Vout and GND pins on J2. The TPS62700 supplies up to 650 mA
of output current.
