The DEFDCDC1, DEFDCDC2, and DEFDCDC3 pins are used to set the output voltage for each step-down
converter. See the table for the default voltages if the pins are pulled to GND or to VCC. If a different voltage is
needed, an external resistor divider can be added to the DEFDCDCx pin as shown in
Table 5
.
The output voltage of VDCDC3 is set with the I
2
C interface. If the voltage is changed from the default, using the
DEFCORE register, the output voltage only depends on the register value. Any resistor divider at DEFDCDC3
does not change the voltage set with the register. Bit B6 in the CON_CTRL2 register is used to switch between
the internal voltage setting or the voltage set with the external DEFDCDC3 pin for the VDCDC3 converter.

Using an external resistor divider at DEFDCDCx:
When a resistor divider is connected to DEFDCDCx, the output voltage can be set from 0.6 V up to the input
voltage V
(bat)
. The total resistance (R1+R2) of the voltage divider should be kept in the 1-MR range in order to
maintain a high efficiency at light load.
