Abstract
A power converter, such as a flyback power converter, configured to send digital information from a secondary side to a primary side of the power converter and notify the secondary side that the communication has been received by the primary side. In this manner the secondary side may receive an acknowledgement (ACK) from the primary side, while maintaining isolation between the primary side and secondary side. To implement the ACK response to digital communication from the secondary side, the primary side may delay generating a PWM pulse to the primary side switch. The secondary side may detect the missing PWM pulse based on a change in the integrated secondary side current and determine that the primary side has sent an ACK response.
