Abstract
A transient recovery circuit in a switching regulator responds to relatively quick changes in load currents to suppress output voltage overshoots or undershoots. The transient recovery circuit operates independently of a regular feedback circuit and overrides a control voltage from the regular feedback circuit to control the duty cycle of a pulse-width modulation circuit in the switching regulator during transient conditions. The transient recovery circuit is inactive during non-transient conditions. The transient recovery circuit can be used in a single phase or a multiphase switching regulator.
