  • Flyback converter with fast load transient detection
    Patent number: 11736026
    Abstract: A flyback converter is provided that detects a load-transient-produced increase in the output current to more quickly detect and respond to the load transient.
    Type: Grant

  • Power adapter having ultra low standby power
    Patent number: 11527962
    Abstract: A standby power system for a flyback converter is disclosed. The flyback converter includes a primary-side, a secondary-side, an output terminal at the secondary-side, and a secondary-side controller, where the output terminal is configured to electrically connect to a load. The standby power system comprises a comparator at the secondary-side, an opto-coupler in signal communication with the primary-side, the secondary-side, and the comparator, and a cable detach detector (or load detector). The cable detach detector is configured to determine whether a device is electrically connected to the flyback converter through a charging cable and to set the flyback converter into a standby mode if the deice is disconnected from the charging cable.

  • 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.
