+ Mode of operation of the dc-to-dc converter
+ Dynamic Power Control (DPC)
+ In this mode, the AD5758 circuitry senses the output voltage and
+ dynamically regulates the supply voltage, VDPC+, to meet compliance
+ requirements plus an optimized headroom voltage for the output buffer.
+
+ Programmable Power Control (PPC)
+ In this mode, the VDPC+ voltage is user-programmable to a fixed level
+ that needs to accommodate the maximum output load required.
+
+ The output of the DAC core is either converted to a current or
+ voltage output at the VIOUT pin. Only one mode can be enabled at
+ any one time.
+
+ The following values are currently supported:
+ * 1: DPC current mode
+ * 2: DPC voltage mode
+ * 3: PPC current mode
+
+ Depending on the selected output mode (voltage or current) one of the
+ two properties must be present:
