Abstract

A voltage generator includes a single inductive element that performs a direct current-to-direct current (DC-DC) conversion on an input voltage to generate a first output voltage, a second output voltage, and a third output voltage, a gate driver which controls the single inductive element, a mode determiner which receives the input voltage, a first feedback voltage generated based on the first output voltage, and a third feedback voltage generated based on the third output voltage and outputs a mode signal, a zero-current detector which is connected to the single inductive element and outputs a zero-current signal, and a controller which receive the mode signal and the zero-current signal and outputs a control signal to the gate driver.
