Abstract
A system and method for minimizing power dissipation in a battery-operated mobile unit by adaptively controlling a voltage converter to provide a variable power supply voltage to a transmitter. In the preferred embodiment, the voltage converter is coupled to receive a source voltage from a battery, and is coupled to provide operating power to the transmitter or the power amplifier. The voltage converter is also coupled to receive a control signal from a controller, which adaptively activates the voltage converter to transform the source voltage to a converted voltage, or deactivates the voltage converter so as to directly apply the source voltage to the transmitter. Power dissipation is therefore minimized when conversion functions of the voltage converter are deactivated when voltage conversion is unnecessary.
