Abstract

A power conversion circuit providing a regulated output voltage to a load can include a switching regulator with an input configured to be coupled to an input voltage source and an output configured to be coupled to the load. The power conversion circuit can further include a metered charge transfer converter, such as a charge pump or a switched or pulsed current source, having an input configured to be coupled to an input voltage source and having an output configured to be coupled to the load. A controller coupled to the metered charge transfer converter can be configured to operate the metered charge transfer converter to deliver energy to the load responsive to a dip of the regulated output voltage below a threshold caused by an increase in current drawn by the load. The metered charge transfer converter may be located closer to the load than the switching regulator.
