Abstract
A power supply device for supplying power to an electronic apparatus with a power saving mode includes a rectifier circuit for converting an AC input voltage Vin to a DC voltage, a boost circuit for boosting the DC voltage to a prescribed level, a power factor correction (PFC) circuit for correcting the power factor of the output voltage of the boost circuit according to a feedback voltage from the output of the boost circuit, and a disable circuit for disabling the power factor correction (PFC) circuit in a power saving mode, whereby the power consumption is prevented for a switching operation of the power factor correction (PFC) circuit in the power saving mode.
