Abstract:
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.

Claim (Index 1):
A primary-side controller for a flyback converter, comprising:\n a communication interface for receiving a control voltage from a secondary-side controller for the flyback converter; a switch controller configured to process the control voltage to determine a desired peak current during a pulse width frequency mode of operation, wherein the switch controller is further configured to cycle off a power switch during a first power switch cycle responsive to a switch current through the power switch equaling the desired peak current; and a waveform analyzer for detecting a transformer reset time from an auxiliary winding voltage, wherein the switch controller is further configured to calculate an average output current from the switch current and the transformer reset time, and wherein the switch controller is further configured to control a cycling of the power switch during a subsequent second power switch cycle independently of the control voltage responsive to the average output current exceeding a current limit.
