Abstract: The invention concerns a system for delivering a voltage to at least one power domain (2.11-2. nz) comprising at least one component, each power domain functioning according to at least two operating points, each operating point defining a required supply voltage, the required supply voltages of the operating points of a given power domain being distinct in pairs. The system comprises at least a first and a second power supply units (1.10-1.n0), each supply unit being adapted to deliver a controllable supply voltage and the at least one power domain comprises at least one first power domain (2.1 x; 2.2y; 2.nz), which is arranged to be alternatively connected to the first or to the second power supply unit. The system further comprises a control unit (5) arranged to select, among the first and second power supply units, a current power supply unit to be connected to the first power domain, the current power supply unit being selected based on a current operating point of the first power domain, the control unit being further arranged to control the controllable supply voltage delivered by the current power supply unit to deliver the required voltage level associated with the current operating point of the first power domain.
