Abstract
According to one embodiment, a flyback power converter comprises a primary circuit including a flyback driver, and an isolated output circuit responsive to the primary circuit. The isolated output circuit is used to power a load. The flyback driver is configured to identify a load current in the isolated output circuit from an input power to the primary circuit, and to regulate the load current according to the input power. In one embodiment, the flyback driver is configured to sense an input voltage to the flyback power converter, to identify an average current value corresponding to a current through a converter switch in the primary circuit, and to multiply the average current value and the input voltage to determine the input power to the primary circuit.
