Abstract: A power management system, which includes a parallel amplifier circuit and a switch mode power supply converter, is disclosed. The switch mode power supply converter cooperatively operates with the parallel amplifier circuit to form the power management system. The power management system operates in one of a high power modulation mode, a medium power modulation mode, and a low power average power tracking mode. Further, during the high power modulation mode and the medium power modulation mode, the power management system controls a power amplifier supply voltage to a radio frequency power amplifier to provide envelope tracking. During the low power average power tracking mode, the power management system controls the power amplifier supply voltage to the radio frequency power amplifier to provide average power tracking.
