Abstract
A tri-level converter provides three levels of power supply to a power amplifier that includes a supply path. The supply path has a first transistor and a first inherent body diode associated with the first transistor, as well as a second transistor and a second inherent body diode associated with the second transistor. A polarity of the second body diode is reversed relative to a polarity of the first body diode. A first driver is configured to drive the first transistor and the first inherent body diode to control a power supply, including a battery supply signal, to an output of the tri-level converter. The tri-level converter is coupled to a switching node.
