  • Patent number: 11594966
    Abstract: A converter circuit includes a half-bridge power circuit with a first and a second switch between an input node and a current node and between the current node ground, respectively. An inductor is coupled between the current node and an output node. Logic control circuitry is configured to switch the first and second switches to a current recirculation state and to a current charge state. The logic circuitry is configured to switch the switches from the current recirculation state to the current charge state as a result of a voltage indicator signal from an output voltage comparator being asserted while starting an on-time counter signal having an expiration value, and from the current charge state to the current recirculation state as a result of the on-time counter signal having reached its expiration value in combination with the voltage indicator signal from the voltage comparator being de-asserted.
