  • Non-dissipative output voltage transition for an isolated switching power converter
    Patent number: 11728736
    Abstract: A flyback converter includes a synchronous rectifier switch transistor controlled by a controller. The controller cycles the synchronous rectifier switch transistor to lower an output voltage by transferring energy from a secondary-side output capacitor to a primary-side input capacitor.
    Type: Grant
