Abstract: An inverting buck voltage converter constructed of a switched-mode hybrid topology, with a capacitive input stage and an inductive output stage. The input stage operates as a charge pump to charge a flying capacitor connected in series with an inductor in the output stage. Clock circuitry generates first and second non-overlapping clock phases. In the second clock phase, the flying capacitor is charged to the input voltage, with a flying node between the flying capacitor and the output inductor connected at ground through a rectifier, while in the first clock phase, the flying capacitor supports the inductor current. The arrangement of the flying capacitor and inductor is such that the voltage appearing at the output terminal is inverted from the input voltage. Continuous output current is provided. Current limiting techniques protect the flying capacitor from overcurrent conditions.

Abstract: An embodiment of the invention provides a method for recording, managing and tracking changes to objects in a computer system. A master record is created for the computer system; and, a transactional record is created for an object in the computer system. The master record includes the current status of the object and the current status for all objects associated to the object. The transactional record is updated in the electronic database; and, the master record is updated when the transactional record is updated. The master record is linked to all of the transactional records of the objects associated to the object with the processor. The master record is updated with the processor when a transactional record of the objects associated to the object is updated or added.
