  • Dual-mode high-side power field-effect transistor driver for power regulators
    Patent number: 12057765
    Abstract: Apparatuses and methods for operating a power converter are described. An integrated circuit can be integrated in a high-side driver of a high-side fiend-effect transistor (FET) of the power converter. The integrated circuit can detect a phase node voltage of a power integrated circuit. The integrated circuit can, in response to the phase node voltage being less than a threshold voltage, operate a high-side FET of the power integrated circuit in a constant-current mode. The integrated circuit can, in response to the phase node voltage being greater than the threshold voltage, operate the high-side FET of the power integrated circuit in a constant-voltage mode.
