Abstract
A driver circuit for a switched-mode power converter is configured to perform hysteretic control of a switched-mode power converter. The switched-mode power converter comprises an inductor configured to store energy during a first state of the switch and to release energy towards a load of the switched-mode power converter during a second state of the switch. The driver circuit comprises a filter unit which is configured to determine a command signal based on a gate control signal applied to a gate of the switch. The command signal is indicative of a current through the inductor. The driver circuit comprises hysteretic control circuitry configured to generate the gate control signal based on the command signal; wherein the switch alternates between the first and second state when being subjected to the gate control signal.
