8.2.2.1 Setting The Output Voltage
With the VSET/MODE pin set high or low, an adjustable output voltage is set by an external resistor divider according to Equation 5:
To keep the feedback (FB) net robust from noise, set R2 equal to or lower than 100 kΩ to have at least 6 μA of current in the voltage divider. Lower values of FB resistors achieve better noise immunity but lower light-load efficiency, as explained in the Design Considerations for a Resistive Feedback Divider in a DC/DC Converter Technical Brief.
When a fixed output voltage is selected, connect the FB pin directly to the output. R1 and R2 are not needed, as VOUT is set through a resistor on the VSET/MODE pin. Select the recommended resistor value from the list in Table 7-2.
