摘要： Disclosed are a feedback circuit and a power supply device including the same. The power supply device converts input voltage into output voltage suitable for load condition according to a switching operation of a power switch. The feedback circuit includes a first diode connected to a first sensing voltage corresponding to output voltage and a second diode connected to the output voltage. The feedback circuit generates feedback voltage by using voltage passing through a conducted diode of the first and the second diodes. The power supply device controls a switching operation of the power switch depending on the feedback voltage.
