Abstract
In an example, a system and method are disclosed for providing a single control law that is operable to regulate both small-signal, steady-state operation, and large-signal transients of a switching regulator. The control law is based on detecting a zero-crossing of capacitor current, and projecting in advance a turning point for either ramping up or ramping down capacitor voltage at a target voltage. Certain embodiments may realize the control function in high-speed analog components, although certain other embodiments may implement the same or a similar control law in a digital controller.
