4.1.1 VSET/VID Resistor (TPSM82866CA3PEVM only)

R4 sets the start-up voltage. To select the desired start-up voltage, leave the jumper off of JP3 when enabling the device. After being enabled, JP3 becomes a VID input pin and selects which VOUT register is active. See the TPSM8286xx 2.4V to 5.5V Input, 4A/6A Step-Down MagPack™ Power Module with Integrated Inductor and I2C interface data sheet for details of the various settings.
