Abstract
In some examples, a controller is configured to control a primary-side switch in a power converter circuit, and the controller includes a first node configured to receive a first signal indicating a current or a voltage through a primary side of a transformer of the power converter circuit. The controller also includes a second node configured to receive a second signal indicating a current or a voltage through a primary-side switch of the power converter circuit. The controller further includes processing circuitry configured to determine a target value for the second signal based on the first signal and generate the control signal for the primary-side switch based on the target value for the second signal.
