Abstract
Disclosed is a digital current sharing structure and method in which a plurality of regulators are configured to share the load current. Current share circuits in each of the regulators are configured to measure and compare the average current provided by that particular regulator with the overall average current provided by all the regulators. Each of the current share circuits then provides an output so that the output of each regulator is adjusted to provide the same amount of current to the load. Digital processing with both analog and digital averaging are disclosed. Also disclosed is a programmable hysteresis technique to eliminate relatively trivial adjustments.
