Patent ID: 8901904

Claim:
A regulator constructed and arranged so as to provide any one of a plurality of desired levels of a regulated signal output to a load, each desired level being a function of a corresponding reference signal, the regulator comprising: (1) a plurality of capacitors, each sized so as to be capable of being charged to a predetermined voltage; (2) a plurality of switches for selectively connecting at least one of the capacitors to the load depending on and as a function of the desired level of the regulated signal output so that when the reference signal is changed, at least one select capacitor is concurrently connected to the load so as to concurrently provide the desired level of the regulated signal output to the load; (3) a control loop having a bandwidth for maintaining the regulated signal output at the desired level; wherein the plurality of switches selectively connect at least one select capacitor to the load as a function of the desired regulated output independently of the bandwidth of the control loop.
