Abstract

A power supply apparatus includes: a detection circuit configured to feed back a voltage to a generation circuit. The detection circuit includes: a first resistor, a second resistor connected in series with the first resistor, a first conductive pattern configured to connect the first resistor and the second resistor in series, a first capacitor connected in parallel to the first resistor, a second capacitor connected in parallel to the second resistor and connected in series with the first capacitor, a second conductive pattern configured to connect the first capacitor and the second capacitor in series, and a third conductive pattern configured to electrically connect the first conductive pattern and the second conductive pattern. A thermal resistance of the third conductive pattern is greater than a thermal resistance of the first conductive pattern.
