Abstract: Aspects of the disclosure provide for a circuit comprising a power converter controller. In an example, the power converter controller is configured to receive a signal representative of a current of a power converter, compare the signal representative of the current of the power converter to an error signal and generate a peak current detection signal having an asserted value when the signal representative of the current of the power converter is not less than the error signal. A state machine circuit is coupled the peak current detection circuit. The state machine circuit is configured to receive the peak current detection signal, a clock signal, and a timer signal and implement a state machine to generate at least one control signal for controlling a mode and a phase of operation of the power converter based on values of the peak current detection signal, the clock signal, and the timer signal.

Abstract: In some examples, an apparatus includes a driver having a driver output, a capacitor having a first plate and a second plate, the first plate coupled to the driver output, and a transistor having a transistor gate, a transistor source, and a transistor drain. The apparatus also includes a first switch coupled between the second plate and the transistor gate, a second switch coupled between the second plate and the transistor drain, and a third switch coupled between the transistor gate and the transistor drain.
