Abstract
A power supply unit includes: a first DC-DC converter that generates a first power supply voltage and a second DC-DC converter that generates a second power supply voltage. The second DC-DC converter includes an inductor, a mode selector that receives at least one signal including information on an inductance value of the inductor and generates an inductor selection driving signal based on the at least one signal, and a feedback loop that receives the inductor selection driving signal and changes a parameter value for generating a current flowing through the inductor based on the inductor selection driving signal.
