Abstract: A voltage generator includes: a transforming unit to transform an input voltage into an output voltage in response to a switching signal; a feedback voltage controller to compare the output voltage with a reference voltage when a start signal is activated, and to output a feedback voltage corresponding to the comparison of the output voltage with the reference voltage; and a power controller to compare the feedback voltage with the reference voltage, and to output the switching signal corresponding to the comparison of the feedback voltage with the reference voltage.
