ABSTRACT:
A system and method are disclosed for providing switch size management in a direct current to direct current (DC-DC) converter circuit for a radio frequency (RF) power amplifier. An output voltage reference signal is provided to a DC-DC converter that comprises a first switch circuit and a second switch circuit. The output voltage reference signal is compared to a threshold voltage. If the output voltage reference signal is lower than the threshold voltage, control circuitry selects a first switch size. If the output voltage reference signal is higher than the threshold voltage, then the control circuitry selects a second switch size. Selecting an appropriate switch size improves the operating efficiency of the DC-DC converter.
