Abstract: A system for delivering a voltage to at least one power domain has at least one component. Each power domain functions according to at least two operating points, each operating point requiring a distinct supply voltage. The system includes at least two power supply units, alternatively delivering controllable supply voltages. The system also includes a control unit that selects one of the power supply units to be connected to a power domain, based on a current operating point of the power domain. The control unit also controls the supply voltage delivered by the selected power supply unit, to deliver the required voltage level associated with the current operating point of the power domain.
