PRODUCTION DATA
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 VO is directly sensed at the VOS pin of the device. VO is sensed only through the VOS pin by an internal resistor divider. The target VO is programmed by an external resistor connected between VSET and GND (see Table 8-2).
