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: A DC/DC switching converter includes high-side and low-side power NFETs coupled in series between a first pin for coupling to a first supply voltage and a second pin for coupling to a second supply voltage. A switch-node is coupled to a third pin. A first gate driver is coupled to drive a gate voltage on the high-side power NFET at a first rate and a second gate driver is coupled to drive the gate voltage of the high-side power NFET at a second rate that is higher than the first rate. A comparator is coupled to the first pin and to the gate of the high-side power NFET and further coupled to turn on the second gate driver when a gate voltage of the high-side power NFET is equal to the first supply voltage coupled to the first pin plus a threshold voltage of the high-side power NFET.
