Abstract
A controller for use in a power converter with multiple outputs includes a discharge detect circuit coupled to receive a voltage signal from a transformer winding of the power converter to output a discharge signal in response to the voltage signal. A multi-output signal process and interface block is coupled to output request signals to the output selection drive and idle ring visibility logic circuit. An output selection drive and idle ring visibility logic circuit is coupled to receive the discharge signal from the discharge detect circuit and the output request signals from the multi-output signal process and interface block. An idle ring detection circuit is coupled to one of the plurality of output switches and coupled to output an idle ring output signal to generate a next request pulse.
