Patent 11955895 was granted and assigned to Dialog Semiconductor PLC on April, 2024 by the United States Patent and Trademark Office.
A flyback converter control architecture is provided in which primary-only feedback techniques are used to ensure smooth startup and detection of fault conditions. During steady-state operation, secondary-side regulation is employed. In addition, current limits are monitored during steady-state operation using primary-only feedback techniques to obviate the need for a secondary-side current sense resistor.
