  • Adaptive startup for switching power converter
    Patent number: 10848054
    Abstract: A switching power supply controller for a switching power supply is provided that measures an input voltage through an application of a load during an input voltage measurement period following connection of the switching power supply to an AC mains. Based upon the measured input voltage, the controller adjusts a start-up delay period so that the start-up delay period is substantially constant despite variations in an AC line voltage for the AC mains.

  • Flyback converter controller with single pin detection of over-voltage and auxiliary winding faults
    Patent number: 10483861
    Abstract: A flyback converter controller is provided with a single terminal through which the flyback converter controller senses for over-voltage faults for an input voltage and also senses for open circuit faults for an auxiliary winding. A first voltage divider provides a divided version of the input voltage to the single terminal. The controller compares a voltage for the single terminal to at least one over-voltage threshold to detect the over-voltage fault for the input voltage.

  • AC line detection and X capacitor discharge using a single terminal
    Patent number: 10170975
    Abstract: A controller for a switching power converter is provided with a single detection pin through which the controller monitors whether the switching power converter is connected to an AC mains. Should a voltage for the detection pin indicate that the switching power converter is disconnected from the AC mains, the controller asserts the detection pin voltage to trigger a bleeder circuit to discharge an X class capacitor.
