DESCRIPTION
NAME
NO.
Input signal indicating default VDCDC1 voltage, 0 = 3 V, 1 = 3.3 V This pin can also be connected to
a resistor divider between VDCDC1 and GND. If the output voltage of the DCDC1 converter is set in
a range from 0.6 V to VINDCDC1 V
Input signal indicating default VDCDC2 voltage, 0 = 1.8 V, 1 = 2.5 V This pin can also be connected
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
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
VDCDC1 enable pin. A logic high enables the regulator, a logic low disables the regulator.
VDCDC2 enable pin. A logic high enables the regulator, a logic low disables the regulator.
VDCDC3 enable pin. A logic high enables the regulator, a logic low disables the regulator.
