Abstract: A power converter is disclosed. The power converter includes a switching circuit coupled to a capacitor and further coupled to a regulated power supply node via an inductor. The switching circuit is configured to magnetize the inductor, using the capacitor, in response to activation of a first control signal, and further configured to charge the capacitor, using an input power supply, in response to activation of a second control signal. A control circuit is configured to activate the first control signal based on a comparison of a first threshold value and a current flowing in the inductor. The control circuit is further configured to activate the second control signal based on a comparison of a second threshold value and the current flowing in the inductor.
