An apparatus may include a power converter having a power supply input for receiving an input power supply voltage generated by a power supply, an output for generating an output voltage to a load, and a power inductor coupled between the power supply input and the output may and further include an energy storage element coupled to the power supply input, the power inductor, and the output such that operation of the power inductor is split temporally between delivering energy to the energy storage element and delivering energy to the load, and operation of the energy storage element is split temporally between delivering energy to the load and receiving energy from one or both of the power supply and the load.
