An envelope tracking power management circuit is disclosed. An envelope tracking power management circuit includes a first envelope tracking amplifier(s) and a second envelope tracking amplifier(s), each configured to amplify a respective radio frequency (RF) signal(s) based on a respective supply voltage. A power management circuit can determine that a selected envelope tracking amplifier, which can be either the first envelope tracking amplifier(s) or the second envelope tracking amplifier(s), receives the respective supply voltage lower than a voltage required to amplify the respective RF signal(s) to a predetermined voltage. In response, the power management circuit provides a boosted voltage, which is no less than the required voltage, to the selected envelope tracking amplifier. As such, it is possible to enable the selected envelope tracking amplifier to amplify the respective RF signal(s) to the predetermined voltage without increasing cost, footprint, and power consumption of the envelope tracking power management circuit.
