  • Internal capacitor linear regulator with transient dip compensator for internal-switch switching regulator
    Patent number: 8975880
    Abstract: A switching regulator arrangement utilizes internal capacitors rather than external capacitors for driving output power transistors. Low-dropout linear voltage regulators together with a dip compensation circuit provide an intermediate supply voltage for driving power transistors under circumstances in which a supply voltage is greater than a gate drive voltage of the power transistor, allowing for a more efficient absorption of transient current.
    Type: Grant

    Date of Patent: March 10, 2015
    Assignee: Broadcom Corporation
