Zusammenfassung:	This document discusses, among other things, apparatus and methods for operating a voltage converter. In an example, a circuit for controlling a converter can include a comparator configured to receive an off-time charge voltage and an off-time threshold and to initiate a transition of a power transistor from an off-time state to an on-time state when the off-time charge voltage exceeds the off-time threshold, and a capacitor coupled to the comparator and configured to receive a voltage from an inductor in the off-time state and to provide the off-time charge voltage using the voltage from the inductor.
