Abstract: The present disclosure includes switching regulator circuits and methods. In one embodiment, a first switching regulator stage receives a first input voltage and produces a first voltage on a first node. A second switching regulator stage receives the first input voltage and produces a second voltage on a second node. A capacitor includes a first terminal coupled to the first node and a second terminal coupled to the second node, and the first switching regulator stage and the second switching regulator stage are configured to set a first voltage on the first node and to set a second voltage on the second node.

Abstract: Embodiments of the disclosure include high slew rate switching regulator circuits and methods. In one embodiment, switching regulators are coupled to an output node. A first switching regulator may drive the output node. A second switching regulator may drive the output node through a capacitor. Control circuitry may include feedback inputs to maintain a first voltage on the output of the first switching regulator on one terminal of the capacitor and further to maintain a second voltage on the output of the second switching regulator on the other terminal of the capacitor.
