Abstract
An amplifier system may include a power stage having inputs for three different supply voltages and an output for coupling to a load, a controller to generate control signals to the power stage that cause the power stage to vary an output voltage applied to the load among more than three distinct voltage levels, a monitor to provide a first control signal to the controller based on an input voltage signal, and a feedback system to provide a second control signal to the controller based on comparison of the output voltage and the input signal.
