8.3.3 Output Voltage Selection

The TPS62743 doesn't require an external resistor divider network to program the output voltage. The device integrates a high impedance feedback resistor divider network that is programmed by the pins VSEL1-3. TPS62743 supports an output voltage range from 1.2 V to 3.3 V. The output voltage is programmed according to Table 6-2. The output voltage can be changed during operation. This can be used for simple dynamic output voltage scaling.
