Abstract

Disclosed examples include a transient event detector circuit to detect transient events in a switching converter, including a DLL circuit to detect changes in a duty cycle of a pulse width modulation signal used to operate a switching converter, and an output circuit to provide a status output signal in a first state when no transient event is detected, and to provide the status output signal in a second state indicating a transient event in the switching converter in response to a detected change in the duty cycle of the pulse width modulation signal.
