  • Circuits and systems for generating power from multiple sources
    Patent number: 12237768
    Abstract: Embodiments of the present disclosure include multiple DC-DC converters configured to generate multiple voltages based on one or more voltage sources. The DC-DC converters are configured to produce a first voltage and second voltage when a first power source is active, when a second power source is active, or when both the first and second power sources are active. In example embodiments, one voltage is used by a network device to power internal circuitry, and another voltage is coupled to tethered devices.
