Abstract
An envelope-tracking (ET) power supply may include a boost control pin. The boost control pin receives a boost enable signal that activates or enables a supplemental power supply in the ET power supply. The supplemental power supply facilitates the generation of a power supply signal for a selected processing stage, e.g., a power amplifier. The supplemental power supply helps the processing stage meet the demands on it caused by the signal that the processing stage needs to handle.
