Abstract: An electronic device includes a switched-mode power supply having a first operating phase during which the output node of the switched-mode power supply is coupled by an on switch to a source of a first reference voltage. The first operating phase is followed by a second operation phase during which the output node of the switched-mode power supply is in a high impedance state. While in the second operating phase, a capacitor connected to the output node of the switched-mode power supply at least partially discharges into a load.
