Abstract
Power-backup capabilities are provided by implementing a variety of different methods, systems and devices. According to one such implementation, a data-storage device is implemented having a memory control circuit controlling nonvolatile and volatile memory. An operating power circuit carries primary-operating power from the host-system to the memories and control circuitry. A backup power circuit includes energy-storage circuitry with one or more energy storage devices. An isolation-regulation circuit provides voltage regulation of power from the host-system and also isolates the host-system provided power from the energy storage devices. A regulation power circuit carries the regulated power from the isolation-regulation circuit to the energy storage devices.
