ABSTRACT:
In one embodiment the present invention includes a voltage converter operable in both buck and boost modes. The voltage converter may only include one switched capacitor. A programmable current source, which may be implemented as a switch array, generates a current into the switch capacitor during a first time period to produce a voltage across the capacitor. During a second time period, the voltage may be transferred to the output of the converter, or boosted by coupling the input voltage to one terminal of the switched capacitor coupling the other terminal of the capacitor to the output. A feedback circuit is coupled to a controller for reprogramming the current into the capacitor to maintain the output voltage at desired levels.
