Abstract

A power voltage generator includes: an input voltage providing part outputting input voltage based on a first signal; an inductor receiving the input voltage to generate an inductor current and connected to an outputting part; the outputting part generating an output voltage based on the inductor current and generating a feedback voltage; an output sensing part sensing the output voltage based on a second signal and generating an output sensing voltage; a peak voltage generator generating a peak voltage based on the input voltage, set data corresponding to an output set voltage, and ripple data corresponding to a ripple set voltage; a first comparing part generating a stop signal based on the output sensing and peak voltages; a second comparing part generating a start signal based on the set data and feedback voltage; and a switch controller generating the first and second signals based on the start and stop signals.
