Systems and methods increase power efficiency in communication systems by examining a digital signal to determine whether a threshold corresponding to an increase in a power requirement is likely to be exceeded. The signal is encoded with information indicating the likely change and communicated to a driver that, upon extracting the information, uses it to cause instruct an amplifier to increase a power output to accommodate the increase in power requirement. Once the threshold is no longer exceeded, the driver circuit, advantageously, decreases the power output to conserve energy. In various embodiments, an amplifier may increase power efficiency by switching from a low-power circuit configuration to a high-circuit configuration.

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.

Various buck-boost amplifier architectures are disclosed. In some architectures, a plurality of amplifiers use one or more inductors from a shared bank of inductors as needed to deliver variable amounts of power to respective loads. In some architectures, each amplifier includes multiple inductors and switches that are controlled to vary the number of inductors used in an amplifier based on a power requirement of the amplifier to drive its load. In some architectures, the switches include well switching devices. In some architectures, each amplifier drives multiple loads and is operated in a single inductor multiple output (SIMO) mode. In all architectures, the loads include speakers, piezo elements, and motors.
