Abstract
In one general aspect, a control circuit for a power converter can include a feedback terminal configured to be coupled to a non-isolated feedback of the power converter when a feedback of the power converter is the non-isolated feedback, or configured to be coupled to a ground when the feedback of the power converter is an isolated feedback. The control circuit can include a detection circuit, coupled to the feedback terminal. The detection circuit can be configured to trigger a feedback voltage at the feedback terminal within an initial setting of the power converter. The feedback voltage can be high in response to the feedback terminal being coupled to the feedback of the power converter, and the feedback voltage can be low in response to the feedback terminal being coupled to the ground of the power converter.
