Abstract
A power converting circuit includes a voltage converting circuit, a feedback circuit, a driving signal generator, a transient state detector, and a resistance value adjuster. The voltage converting circuit changes a voltage level of an input voltage responsive to a driving signal, and outputs an output voltage according to the changed voltage level of the input voltage. The feedback circuit divides the output voltage to output the divided output voltage as a feedback voltage. The driving signal generator compares a level of the feedback voltage with a level of a reference voltage and outputs the driving signal. The transient state detector compares the level of the feedback voltage with the level of the reference voltage and outputs a transient state signal corresponding to a transient state of the output voltage. The resistance value adjuster adjusts the feedback resistance value, which divides the output voltage, responsive to the transient state signal.
