ABSTRACT:
A managing system manages a plurality of VRMs associated with a plurality of microprocessors and connected in parallel together between first and second voltage references, the VRMs having output terminals connected together and arranged to communicate over a common bus. The managing system includes an error amplifier being input an output voltage signal from the VRM plurality, a reference voltage, and a droop voltage produced through an equivalent droop resistor receiving an output current signal from the VRM plurality and being connected to the common bus. The error amplifier effects a comparison of the input signals to generate a control voltage signal to the VRM plurality. Advantageously, the managing system comprises a controller connected to the equivalent droop resistor.
