Original Abstract Submitted
Embodiments herein relate to a driver for a voltage converter which efficiently generates a control gate voltage of a power switch. The driver applies a staircase increasing and decreasing voltage to the control gate with three or more voltage levels, including an initial level such as 0 V, one or more intermediate voltages, and a peak drive voltage. The one or more intermediate voltages can be generated by a charge-recycling circuit which can include push-pull capacitors or switched flying capacitors. The push-pull capacitors are provided in a number of push-pull regulation circuits which is equal to the number of intermediate voltages. The switched flying capacitors are provided in a circuit where the number of flying capacitors is equal to the number of intermediate voltages.
