Abstract

A multiphase switching converter includes a first switching converter circuit including a power stage coupled to a DC voltage supply and a controller. The controller includes an over-current (OC) circuit that can detect an OC event and, upon detecting the OC event, set a command signal to a preset low value and provide a first hiccup signal. A synchronization circuit can generate a second hiccup signal based on the command signal of the OC circuit satisfying a first reference threshold value, and a sampled portion of an output voltage of the power stage satisfying a second reference threshold value. A hiccup timer can be triggered by one of the first hiccup signal or the second hiccup signal to start a hiccup pulse in response to being triggered.
