Abstract
A single-inductor DC-DC converter generates two DC output voltages at two capacitors. The converter selectively transfers energy from a battery to the inductor or from the inductor to a selected capacitor. While the converter is still settling, the converter is regulated based on only the more deficient DC output voltage. After the converter has already settled, the converter is regulated based on the common-mode voltage for both DC output voltages. By regulating the still-settling converter based on only the more deficient DC output voltage, instead of the common-mode voltage, even greater deficiencies in that already more-deficient DC output voltage are avoided.
