Abstract
A system, power supplies, controller and method for enhanced phase current sharing are disclosed. For example, a power supply for enhanced phase current sharing is disclosed, which includes a plurality of power modules, a communication bus coupled to an input of each power module of the plurality power modules, and an output voltage node coupled to a first side of an inductor of each power module of the plurality of power modules, wherein each power module of the plurality of power modules includes a digital controller coupled to the input of the power module, and an RC circuit enabled to generate a feedback signal, coupled to a second side of the inductor and the output voltage node. In some implementations, the power supply is at least part of a power management integrated circuit (PMIC) or at least part of a power supply formed on a semiconductor IC, wafer, chip or die.
