Zusammenfassung:A system includes a load and a switching converter coupled to the load. The switching converter includes at least one switching module and an output inductor coupled to a switch node of each switching module. The switching converter also includes a controller coupled to each switching module, where the controller is configured to adjust a pulse clock rate and a switch on-time for each switching module. The controller comprises a pulse truncation circuit configured to detect a voltage overshoot condition and to truncate an active switch on-time pulse in response to the detected voltage overshoot condition.
