In a method and system for providing isolated power, a flyback controller includes a transformer operable to receive a primary voltage input and generate a secondary voltage output. A switch electrically coupled in series with a primary side of the transformer receives a control signal for controlling a duty cycle of the primary voltage. A controller is operable to generate the control signal responsive to receiving a plurality of inputs from the primary side. The controller regulates the secondary voltage output without receiving feedback input from a secondary side of the transformer by computing the secondary voltage as a predefined function of the plurality of the inputs when the switch is open.
