摘要： An apparatus includes hardware circuits, a front-end power supply, voltage regulators, and control circuitry. The front-end power supply generates electrical power for the hardware circuits. The front-end power supply includes power stages that generate portions of electrical power and are activated and deactivated independently. The voltage regulators are connected to an output of the front-end power supply and provide adjustable operating voltages to the hardware circuits. The control circuitry controls the voltage regulators to supply the adjustable operating voltages responsively to requests from the hardware circuits, compares the adjustable operating voltages to settings that are specified as safe for provisioning by a predefined partial number of the power stages of the front-end power supply, and adaptively activates and deactivates the power stages, including ensuring that a number of active power stages is set to the predefined partial number only while the operating voltages match the safe settings.
