I
to a resistor divider between VDCDC2 and GND. If the output voltage of the DCDC2 converter is set
in a range from 0.6 V to VINDCDC2 V.
Input signal indicating default VDCDC3 voltage, 0 = 1.3 V, 1 = 1.55 V This pin can also be connected
DEFDCDC3
1
I
to a resistor divider between VDCDC3 and GND. If the output voltage of the DCDC3 converter is set
in a range from 0.6 V to VINDCDC3 V.
