Abstract

Currents flowing in the various channels within a voltage regulator module (VRM) are suitably converted to digital equivalents that can be processed to control each module in a modular power supply. Functions that may be digitally implemented include current balancing between channels, current sharing between various modules in a power supply, and/or the like. By monitoring the current provided on each channel within a module, for example, a controller can determine an average current for the channels, which in turn can be used to identify and compensate for over- or under-production in any particular channel. Active voltage positioning techniques and overload protection may also be implemented using digital techniques.
