Abstract
A tracking power converter for a radio frequency power amplifier includes a boost converter circuit, a switching network circuit, a filter circuit, and a controller circuit. The boost converter circuit provides a boosted voltage in response to a battery voltage. The switching network provides a switching signal in response to the boosted voltage, a first switch enable signal, a second switch enable signal, and a third switch enable signal. The filter circuit provides a power converter output voltage in response to the switching signal. The controller circuit provides the first switch enable signal, the second switch enable signal, and the third switch enable signal in response to a predetermined reference voltage, the switching voltage, the boosted voltage, and the battery voltage.
