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 1):
A power converter comprising:\n a first switch to be coupled to a primary winding of a transformer; a second switch to be coupled to a secondary winding of the transformer; a first control circuit having an input to be coupled to an auxiliary winding of the transformer, and an output to provide a first switching control signal to a first control terminal of the first switch, the first switching control signal configured to initiate a power transfer cycle actuated by the first switch in response to a predetermined cycle start request signal received by the input; and a second control circuit having an output to provide a second switching control signal to a second control terminal of the second switch, the second control circuit configured to generate the second switching control signal triggering the predetermined cycle start request signal and in response to detecting a current of the secondary winding returning to zero.
