Abstract

A DC-DC converter with droop regulation for better transient performance. The DC-DC converter includes a switching circuit, a comparison circuit and a logic control circuit. A differential voltage indicative of an output voltage of the switching circuit, and a droop voltage indicative of an output current of the switching circuit, are generated. A high-pass filtered signal is obtained by high-pass filtering the droop voltage. The comparison circuit responds to the differential voltage, a reference voltage and the high-pass filtered signal to generate a set signal. The logic control circuit generates a control signal based on the set signal to control the switching circuit.
