Abstract
A programmable parameter or feature is provided for a power converter through a multi-function connection on the converter controller. The parameter or feature selection is active for programming during a startup mode, and the connection is used for other control purposes during a steady state run mode. A reference signal is read on the multifunction connection during startup mode and a selection of a parameter value or feature is made based on a value of the reference signal. The reference signal is compared to preset, internal reference values to select a desired parameter value or feature. An internal preset value is chosen based on the selection and the programming circuitry is disconnected from the connection to permit alternate functionality for the connection. The programmable circuit permits selection from a variety of parameter values or features based on an external signal, without dedicating an external pin on the controller.
