Abstract

A method is provided. A first reference voltage during an idle mode is selected, and the first reference voltage is applied to a switched-mode converter. A first output voltage is then generated by the switched-mode converter from a power supply, and a capacitor is overcharged with the first output voltage. The first output voltage is regulated to generate a second output voltage during the idle mode. Then, a second reference voltage during a quiet mode, where the second reference voltage to the buck converter. During the quiet mode, a third output voltage is generated from the switched-mode converter and from discharging the overcharged capacitor, and the third output voltage is regulated to generate the second output voltage.
