Classification: CPC H  G | IPC H

Claim 0:
1. An electronic device, comprising:
a power rail configured to provide a rail voltage;
a plurality of voltage regulators electrically coupled to the power rail and configured to provide the rail voltage collectively, each of the plurality of voltage regulators including:
an output interface coupled to the power rail and configured to provide the rail voltage and deliver up to a predefined regulator current to the power rail;
one or more drive paths coupled to the output interface and configured to operate with an operating frequency;
a voltage regulator controller having an output coupled to the one or more drive paths and an input coupled to the output interface by a feedback path, and configured to control the one or more drive paths; and
a bypass unit coupled to the one or more drive paths and the voltage regulator controller;

wherein each respective voltage regulator of the plurality of voltage regulators is configured to operate, in accordance with a control setting, in either a standby mode in which the bypass unit is enabled to bypass the feedback path from the output interface to the input of the voltage regulator controller and the respective voltage regulator does not deliver current to the power rail, or an operational mode in which the bypass unit is disabled from bypassing the feedback path and the respective voltage regulator delivers up to the predefined regulator current to the power rail.
