Abstract
Voltage regulating systems are provided that adjust their output control signals in response to feed-forward information that is indicative of deterministic changes in the load current. A feed-forward circuit provides a feed-forward signal in response to an input signal generated from a source that is external to the voltage regulating system. The voltage regulator systems can proactively respond to the predictive information by adjusting their output, thereby improving the regulation tolerance to dynamic loading. As an example, the feed-forward information can include signals indicating multiple deterministic events that affect the load. Signals from multiple events can be summed together to generate a feed-forward term. As another example, the voltage regulating systems can be responsive to feedback information and feed-forward information from internal to the regulator, in addition to external deterministic information.
