CIRCUITS AND METHODS FOR PROVIDING CURRENT TO A LOAD

摘要

The present disclosure includes switching regulator circuits and methods. In one embodiment, cross coupled circuits are provided. In one embodiment, a first switching regulator stage has an output coupled to a first node, and a second switching regulator stage has an output coupled to a second node. The first switching regulator stage includes a feedback input coupled to the second node, and the second switching regulator stage includes a feedback input coupled to the first node. The first and second nodes may be coupled together through a capacitor.

1. A method comprising:
sensing, by a first circuit, a first voltage on a first node coupled to a load, wherein the first circuit comprises an output coupled to a second node, and the second node is coupled to the first node through a first capacitor; sensing, by a second circuit, a second voltage on the second node, wherein the second circuit comprises an output coupled to the first node; providing a first current to the load by the first circuit through the first capacitor over a first time period to maintain the first voltage at a first voltage value; and changing a second current to the load by the second circuit over a second time period in response to a change in the second voltage to maintain the second voltage at a second voltage value, wherein the first time period is less than the second time period.
