A typical power switch in a Buck Regulator requires a pre-driver to ensure rapid transition from its ON to OFF states. In this invention, the shoot through current in the pre-driver and the power switchs gate-charge in a Buck regulator is itself recaptured in the capacitor of the buck regulator. The recapturing of this otherwise wasted shoot-through current and gate charge allows for increased efficiency of the regulator. The recapture may be selectively disabled to accommodate high power operations of the system, if such are used the recapture may in an alternative mode be always performed. As a result, reduced power consumption can be achieved.
