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 9):
A method for a flyback converter, comprising:\n in a secondary-side controller for the flyback converter, comparing an output voltage for the flyback converter to a reference voltage to determine a control voltage; transmitting the control voltage from the secondary-side controller to a primary-side controller; in a pulse width modulation mode of operation for the flyback converter, processing the control voltage to determine a desired peak current for a power switch; following a cycling on of the power switch in a first power switch cycle, switching off the power switch responsive to a current through the power switch equaling the desired peak current; following the switching off of the power switch, determining a transformer reset time from an auxiliary winding voltage; and determining an average output current for the flyback converter from the transformer reset time and the current through the power switch.
