Abstract
In a described example, a circuit can include a reference controller and a gain adjuster. The reference controller is configured to sample an input voltage from an input stage of the circuit and generate a modulation signal based on a square of the input voltage and an output current of an output stage of the circuit using an error amplifier. The modulation signal is configured to modulate conduction of a switch of a power factor correction (PFC) converter of the circuit to cause an average output current of the output stage of the circuit to follow a reference proportional to the square of the input voltage. The gain adjuster is configured to adjust a gain of the error amplifier based on the input voltage.
