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.
