Claim 0:
1. A power voltage generator comprising:
an input voltage providing part configured to output an input voltage in response to a first switch control signal;
an inductor configured to receive the input voltage to generate an inductor current and connected to an outputting part;
the outputting part configured to generate an output voltage based on the inductor current and to generate a feedback voltage corresponding to the output voltage;
an output sensing part configured to sense the output voltage in response to a second switch control signal and to generate an output sensing voltage;
a peak voltage generator configured to generate 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 configured to generate a stop signal based on the output sensing voltage and the peak voltage;
a second comparing part configured to generate a start signal based on the set data and the feedback voltage; and
a switch controller configured to generate the first switch control signal and the second switch control signal based on the start signal and the stop signal.
