Claims15
A method comprising:
- determining a switching frequency of a switched mode power supply that includes capacitors;
- and
- responsive to determining that the switching frequency of the switched mode power supply is within an audio band, adjusting the switching frequency of the switched mode power supply to a different frequency within the audio band.
A switched mode power supply comprising:
- one or more switches;
- a capacitor;
- and
- a controller configured to:
- determine a switching frequency of the one or more switches;
- and
- adjust, responsive to determining that the switching frequency is within an audio band, the switching frequency to a different frequency within the audio band.
