Abstract
System and methodology for controlling output current of switching circuitry having an input circuit and an output circuit electrically isolated from each other. A value of the output current may be determined based on input voltage, input current and reflected output voltage representing the voltage in the input circuit which corresponds to the output voltage. A switching element in the input circuit is controlled to produce the determined value of output current.
