ABSTRACT:
A circuit with an isolation interface and a remote on/off function is disclosed. The circuit includes a controller included in a primary side of the circuit. The controller is coupled to receive a primary side feedback signal and the controller is configured to enter a shutdown mode when the primary side feedback signal exceeds a feedback signal threshold. The circuit also includes an isolation interface coupled to galvanically isolate the primary side from a secondary side of the circuit. The isolation interface translates a secondary side feedback signal from the secondary side into the primary side feedback signal on the primary side. The isolation interface is configured to adjust the primary side feedback signal to exceed the feedback signal threshold in response to an on/off signal.
