Abstract:
A method and apparatus to control a voltage conversion mode in a voltage converter are provided. The apparatus to control a voltage conversion mode includes: a voltage converter which converts an input voltage to an output voltage and having a plurality of voltage conversion modes; an input sensor which detects an input current value that is input to the voltage converter from a voltage source; an output sensor which detects an output current value that is output to a load from the voltage converter; and a controller which determines a power efficiency of the voltage converter based on the input and output current values and which switches between the voltage conversion modes of the voltage converter according to the detected power efficiency. Accordingly, an efficiency of voltage conversion is maximized, and a usage time of a mobile device can be lengthened.
