Abstract
A control circuit for a switched mode power converter is adapted to receive a current sense signal reflecting the output current of the power converter and a feedback signal reflecting the output voltage of the power converter. The control circuit includes a first over-current protection circuit adapted to shut off operation of the switched mode power converter if a sum of the current sense signal and the feedback signal exceed a first predetermined limit, and a second over-current protection circuit adapted to regulate operation of said primary side power switch responsive a comparison of the sum of the current sense signal and the feedback signal to a second predetermined limit. The second predetermined limit is less than the first predetermined limit.
