The invention relates to a method for provision of a drive signal for a switch which controls the current drawn by an inductive energy storage element in a power factor correction circuit, in which a control signal which controls the power consumption is available. One drive cycle of the switch comprises: detection of a predetermined storage state of the inductive energy storage element; when the predetermined storage state of the storage element is detected, production of a switching-on level for the drive signal for a regular switched-on duration which is dependent on the control signal or for a maximum switched-on duration which is dependent on an input voltage, when the regular switched-on duration is greater than the maximum switched-on duration; and production of a switching-off level for the drive signal for a switched-off duration until the next detection of the predetermined storage state.
