ABSTRACT:
A power supply with a power factor correction circuit for use in a display monitor controls a switching power circuit in response to a voltage induced at a secondary winding of a transformer provided in the power factor correction circuit. Further, upon receiving a power saving control signal generated from a microcomputer provided in the display monitor, the power supply operates in the stand-by mode, (i.e., the power saving mode), in which only the power saving mode power supply circuit operates to supply operational power to the microcomputer.
