ABSTRACT:
A digital controller for controlling an output regulator. The digital controller having sub-blocks for providing functions to control the output regulator. An energy saving discontinuous mode (ESDM) controller to monitor a sense point of the output regulator. The sense point to indicate a power state of the output regulator and the ESDM controller to control a flow of power to the sub-blocks to control power consumption of the digital controller as a function of the power state of the output regulator.
