  • Energy recovery during system shutdown
    Patent number: 11460902
    Abstract: Presented herein are methodologies for providing power for last gasp operations of a circuit board when power is unexpectedly interrupted. A method includes monitoring a voltage of a main power supply; when the voltage of the main power supply falls below a predetermined threshold, disabling a first point of load (POL) converter that is being powered by the main power supply; boosting a voltage of an output capacitor of the first point of load converter to obtain a boosted voltage; and supplying the boosted voltage to an input of a second point of load converter.
    Type: Grant
    Filed: November 8, 2019
    Date of Patent: October 4, 2022
    Assignee: CISCO TECHNOLOGY, INC.
