Abstract
A voltage converter for use in a backlight module stores energy of an input voltage using an inductor and outputs a plurality of output voltages accordingly. The charging path of the inductor is controlled according to the first output voltage so that the first output voltage can be stabilized. The discharging paths from the inductor to other output voltages are controlled according to the differences between other output voltages and the first output voltage so that other output voltages can also be stabilized.
