Summary: | A power factor correction controlling circuit includes a control signal providing circuit configured to provide a control signal associated with a feedback signal, the feedback signal being controlled based on a bias signal, a pulse width modulation signal controlling circuit configured to control a pulse width modulation signal based on one of first and second bias signals and a power factor controlling circuit configured to provide a power factor control signal when an amplitude of the pulse width modulation signal reaches that of the power factor control signal. Such a circuit Is able to operate stably, regardless of a load condition and an input voltage condition. |
