Abstract
In a provided power supply unit, a plurality of circuit elements are integrated into a chip, wherein the circuit elements generate one or more output voltages by using an input voltage. Thus, although the number of voltages, which can be generated by the power supply apparatus, is remarkably large, the power supply apparatus can be miniaturized. In addition, an apparatus, in which the power supply apparatus is installed, can be miniaturized.
