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:
