In the illustrated embodiment, the first switch S₁ includes a first end electrically connected to the battery voltage V_BATT and a second end electrically connected to a first end of the second switch S₂ and to a first end of the inductor 1075. The second switch S₂ further includes a second end electrically connected to a first or ground supply V_GND. Although FIG. 10 illustrates a configuration of a DC-to-DC converter that is powered using a ground supply and a battery voltage, the teachings herein are applicable to DC-to-DC converters powered using any suitable power supplies. The inductor 1075 further includes a second end electrically connected to a first end of each of the third to sixth switches S₃-S₆. The third switch S₃ further includes a second end electrically connected to the ground supply V_GND. The fourth, fifth, and sixth switches S₄-S₆ each include a second end configured to generate the first, second, and third regulated voltages V_MLS1, V_MLS2, and V_MLS3, respectively.

The first to sixth switches S₁-S₆ are selectively opened or closed to maintain regulated voltages within a particular error tolerance of target voltage levels. Although an example with three regulated voltages is shown, the MLS DC-to-DC converter 1073 can be implemented to generate more or fewer regulated voltages.

In the illustrated embodiment, the MLS DC-to-DC converter 1073 operates as a buck-boost converter operable to generate regulated boost voltages greater than the battery voltage V_BATT and/or regulated buck voltages lower than the battery voltage V_BATT. However, other implementations are possible.
