A full digital power AC to DC Switched-Mode Power Supply (SMPS) system includes both digital power control and digital power management. In digital power control, the control feedback or feed-forward loop that regulates the output of the power system is directly controlled by a 56800/E Digital Signal Controller (DSC) by driving a power switch duty cycle using a pulse width modulation technique. The DSC also provides the digital power management function, which provides configuration, tracking, monitoring, protection, guiding supply sequence, and communication capabilities. In a more traditional approach, the power control function would be performed using analog circuitry while the power management would be performed with a Microcontroller.
