MULTI-LEVEL DRIVING FOR EFFICIENT SWITCHING REGULATORS
This abstract first appeared for US patent application 20250096787 titled 'MULTI-LEVEL DRIVING FOR EFFICIENT SWITCHING REGULATORS
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.
