  • Patent number: 9548714
    Abstract: A controller and an output filter for a power converter, and a power converter employing at least one of the same. In one embodiment, the controller includes an error amplifier with first and second input terminals coupled to one of an operating characteristic and a reference voltage of the power converter, and a switch configured to couple the first and second input terminals to one of the operating characteristic and the reference voltage as a function of a power conversion mode of the power converter. In one embodiment, the output filter includes an output filter capacitor with a first terminal coupled to a first output terminal of a power converter, and an output filter inductor coupled between a second terminal of the output filter capacitor and a second output terminal of the power converter.
