The DEFDCDC1, DEFDCDC2, and DEFDCDC3 pins are used to set the output voltage for each step-down
converter. See Table 4 for the default voltages if the pins are pulled to GND or to Vcc.

external voltage divider
0.6V to VinDCDC3
If a different voltage is needed, an external resistor divider can be added to the DEFDCDC1 or DEFDCDC2 pin
as shown below:
When a resistor divider is connected to DEFDCDC1 or DEFDCDC2, the output voltage can be set from 0.6V up
to the input voltage Vbat. The total resistance (R1+R2) of the voltage divider should be kept in the 1M range in
order to maintain a high efficiency at light load. VDEFDCDCx = 0.6V
The output voltage of VDCDC3 is set with an external resistor divider at DEFDCDC3. This pin must not be
connected to GND or VINDCDC3. The value of the resistor divider can be changed during operation to allow
dynamic voltage scaling.
