Disturbance quelling

An apparatus for quelling a disturbance at an output thereof, said apparatus comprising a control system that is configured to anticipate a change in an operating mode of a regulator that is a constituent of a power converter that comprises a charge pump and said regulator, wherein said control system is configured to receive information indicative of a forthcoming transition between regulator modes and, in response to receiving said information, to take action prior to said transition, said action having the effect of suppressing evidence of occurrence of said transition at said output when said transition later occurs.

An apparatus comprising a controller that is configured to control operation of a power converter that supplies a constant output voltage at an output thereof, said power converter including a regulator that connects to a charge pump, wherein said charge pump and said regulator are operable in plural charge-pump modes and plural regulator modes respectively, and wherein said controller is configured to receive information indicative of a forthcoming transition between said regulator modes and in response, to suppress evidence of said transition before it manifests at said output.
