Abstract
A voltage converter can be switched among two or more modes to produce an output voltage tracking a reference voltage that can be of an intermediate level between discrete levels corresponding to the modes. One or more voltages generated from a power supply voltage, such as a battery voltage, can be compared with the reference voltage to determine whether to adjust the mode. The reference voltage can be independent of the power supply voltage. Further, the voltage converter may implement frequency modulation and a pulse skipping mode to improve the efficiency of switching operational states of the voltage converter.
