Abstract
A first switch couples an input node receiving a main control signal for a main switching stage of a multi-phase converter to an output node delivering a secondary control signal for a secondary switching stage following actuation of the secondary switching stage. A second switch couples the output node to a capacitor during a time period of actuation/deactuation of the secondary switching stage. Current is sourced to the capacitor during the actuation time period or sunk from the capacitor during the deactuation time period. The sourced or sunk current may be generated proportional to the main control signal.
