Abstract
A DC-to-DC switching power converter includes switching elements having capacitive gate control inputs, an energy storage element and driver circuitry. Improved efficiency is achieved using adiabatic buffers to drive MOSFET switching elements with stepped switching signals. Substantially equal rise and fall times are achieved. In one embodiment, the switching power converter is fabricated on a semiconductor die to generate an output voltage to one or more functional unit blocks on the die.
