Abstract
A power stage of a voltage regulator includes a first switch for connecting a load to a supply voltage in a first switching state of the power stage, a second switch for connecting the load to ground in a second switching state of the power stage and driver circuitry for setting the power stage in the first switching state, the second switching state or a non-switching state in which both switches are off responsive to a switching control signal received by the power stage. A power management unit moves the power stage from a nominal power mode to a first low power mode if the power stage is in the non-switching state for a predetermined time period.
