Claim Text:
1. An interruption protection system for a supplied load, comprising: a power supply configured to provide power for the supplied load; a capacitor configured to provide buffer energy; a charge pump electrically coupled to the capacitor to charge the capacitor to a buffer voltage; a reference unit configured to provide a reference signal; a controller coupled to the power supply and to the reference unit and configured to receive the reference signal and to selectively control one or more supply paths from the power supply and from the capacitor to power the supplied load based on a comparison of the reference signal and a voltage level of the power supply; and at least one storage pass device coupled to the controller and to the capacitor, wherein the at least one storage pass device is coupled in the supply path between the capacitor and the supplied load, and wherein the controller is configured to control the at least one storage pass device to selectively control a current flow from the capacitor to the supplied load.
