Abstract
A DC-DC converter selectively operates in at least a first burst mode having at least one first-mode charge cycle with a first-mode charging phase followed by a first-mode discharging phase or a second burst mode having at least one second-mode charge cycle with a second-mode charging phase followed by a second-mode discharging phase. A first-mode charging phase is terminated when an inductor current flowing through the inductance reaches a first-mode peak-current threshold, and a first-mode discharging phase is terminated when the inductor current reaches a first-mode valley-current threshold. A second-mode charging phase is terminated when the inductor current reaches a second-mode peak-current threshold, wherein the second-mode peak-current threshold is different from the first-mode peak-current threshold, and the second-mode discharging phase is terminated when the inductor current reaches a second-mode valley-current threshold, wherein the second-mode valley-current threshold is different from the first-mode valley-current threshold.
