  • Methods and systems of controlling switching frequency of a switching power converter
    Patent number: 11196348
    Abstract: Controlling switching frequency of a switching power converter. At least some example embodiments are methods of operating a switching power converters, comprising: operating, by a primary-side controller, a switching power converter at a first frequency set by a resistor coupled to a first pin of the primary-side controller; and sensing a synchronization signal applied to the first terminal of the primary-side controller, the synchronization signal has a second frequency that is variable; and operating, by the primary-side controller, the switching power converter at the second frequency.
