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.
