Abstract
The present disclosure relates to power supply circuitry that has wide bandwidth and achieves high efficiency by using at least one energy storage element for efficient power transfer between two power supply circuits and to an amplitude modulated load. Specifically, the power supply circuitry may include a first power supply circuit, which may be a switching power supply circuit, a second power supply circuit, which may be a linear power supply circuit and may include the energy storage element, and control circuitry to facilitate efficient power transfer. The control circuitry may select one of multiple operating modes, which may include a first operating mode, during which the first power supply circuit may provide power to the energy storage element, and a second operating mode, during which the second power supply circuit may provide power to the amplitude modulated load from the energy storage element.
