  • CHARGE-CYCLE CONTROL FOR BURST-MODE DC-DC CONVERTERS
    Publication number: 20210211055
    Abstract: A DC-DC converter operates in a burst mode having at least one charge cycle with a charging phase followed by a discharging phase. A charging phase is terminated when an inductor current flowing through an inductance connected to the DC-DC converter reaches a compensated peak-current threshold, wherein the compensated peak-current threshold compensates for charging-phase loop delay. A discharging phase is terminated when the inductor current reaches a compensated valley-current threshold, wherein the compensated valley-current threshold compensates for discharging-phase loop delay.
