Abstract
An apparatus includes a voltage converter to convert an input voltage to an output voltage. The voltage converter includes a first set of switches operated during a first switching phase. The voltage converter further includes a second set of switches operated during a second switching phase. The duration of the second switching phase is related to the duration of the first switching phase.

15. A method of operating a voltage converter, the method comprising:
-
operating a first set of switches in the voltage converter for a first duration; and operating a second set of switches in the voltage converter for a second duration, wherein the second duration is derived from the first duration in order to trade off an efficiency of the voltage converter with an output-voltage ripple of the voltage converter. - View Dependent Claims (16, 17, 18, 19, 20)
