Abstract
A first system includes first and second buck-boost amplifiers. The first amplifier is connected to a battery, includes a first inductor and a first plurality of switches connected to the first inductor, and drives first and second loads. The second amplifier is connected to the battery, includes a second inductor and a second plurality of switches connected to the second inductor, and drives the first and second loads. A controller drives the first and second plurality of switches to operate each of the first and second amplifiers in a single inductor multiple output mode. A second system includes multiple buck-boost amplifiers connected to a battery and driving respective loads. Each amplifier includes inductors and switches connected to the inductors. A controller drives the switches to utilize one or more inductors based on an amount of power used by each amplifier to drive the respective loads.
