System and method for controlling overshoot and undershoot in a switching regulator

摘要

A system and a method are disclosed for controlling overshoot and undershoot in a switching regulator circuit. A first comparator circuit for controlling an undershoot of an output voltage of the switching regulator circuit is provided that that detects an occurrence of an undershoot of the output voltage of the switching regulator circuit and activates a first current source to pull up the output voltage of the switching regulator circuit. A second comparator circuit for controlling an overshoot of an output voltage of the switching regulator circuit is provided that detects an occurrence of an overshoot of the output voltage of the switching regulator circuit and activates a second current source to pull down the output voltage of the switching regulator circuit.
