8.3.3 Selectable V_O Operation (VSET and Internal Voltage Divider)

If the device is configured to VSET operation, the device interprets the VSET pin value following the MODE/S-CONF readout (see Figure 8-3). There is no further interpretation of the VSET pin during operation and the output voltage cannot be changed afterward without toggling the EN pin.

Figure 8-3 shows the typical schematic for this configuration, where V_O is directly sensed at the VOS pin of the device. V_O is sensed only through the VOS pin by an internal resistor divider. The target V_O is programmed by an external resistor connected between VSET and GND (see Table 8-2).
