Abstract
A resonant mode power converter is controlled with a control unit including a current limiting circuit coupled to receive a first current representative of a power converter output and a second current generated in response to a reference voltage. The current limiting circuit is coupled to limit the first current in response to the second current. An oscillator is coupled to receive the first current to generate a control signal having a control frequency in response to the first current. The power converter output is controlled in response to the control frequency of the control signal.
