Abstract:
Disclosed examples include flyback converters, control circuits and methods to facilitate secondary side regulation of the output voltage. A primary side control circuit operates a primary side switch to independently initiate power transfer cycles to deliver power to a transformer secondary winding in a first mode. A secondary side control circuit operates a synchronous rectifier or secondary side switch to generate a predetermined cycle start request signal via a transformer auxiliary winding to assume secondary side regulation and to cause the primary side controller to initiate new power transfer cycles.

Claim (Index 8):
A control circuit for use in a power converter to control a switch coupled to a primary winding of a transformer, the control circuit comprising:\n a driver circuit to provide a switching control signal to the switch; and a logic circuit coupled to the driver circuit, and including an input to be coupled to an auxiliary winding of the transformer to receive a feedback voltage, the logic circuit configured to generate the switching control signal to initiate a power transfer cycle actuated by the switch in response to detecting an interruption in a ringing pattern of the feedback voltage.
