Abstract
Direct current-direct current (DC-DC) converters including buck converters are described. These DC-DC converters may be configured to reduce oscillations that would otherwise arise in the output reference voltage due to ringing effects without significantly lengthening the duration of the transient period. These DC converters may leverage a feedback voltage generated by sensing the current flowing through the inductor of the buck converter. The feedback voltage may compared to a threshold, and the signal resulting from the comparison may be used to vary the reference voltage. The DC-DC converter may be operated in a 'partial reset mode,' in which the voltage generated by sensing the inductor's current is reduced to a value greater than zero in response to the feedback voltage reaching the threshold. Reducing the sense voltage in this manner may reduce the duration of the transient period.
