ABSTRACT:
A power supply apparatus having multiple outputs, a transformer, a first output circuit generating a first output voltage with respect to power transferred to a secondary side of the transformer, and a first output controller generating a first control signal to control a power supply provided to a primary side of the transformer, the apparatus including: a second output circuit to generate a second output voltage with respect to the power transferred to the secondary side of the transformer; and a second output controller to control an output of the second output voltage, wherein the second output circuit includes a second switch performing a switching operation on current flows of the second output circuit, and the second output controller controls the switching operation of the second switch by turning off the second switch or feeding the second output voltage back to the second switch according to the first control signal.
