Abstract
A power amplifier (PA) envelope power supply and a process to select a converter operating mode of the PA envelope power supply are disclosed. The PA envelope power supply operates in one of a first converter operating mode and a second converter operating mode. The process for selecting the converter operating mode is based on a selected communications mode of a radio frequency (RF) communications system, a target output power from RF PA circuitry of the RF communications system, and a direct current (DC) power supply voltage.
