A soft-start circuit for a power converter including a switch controlled to cause the soft-start interval for a converter to be terminated when a predetermined condition is fulfilled. The predetermined condition is preferably generated when the output voltage of the converter stabilizes at its normal operational level. The circuit detects when the predetermined condition is fulfilled and enables the converter to more rapidly recover after the initiation of a soft-start. In a preferred embodiment, the soft-start circuit includes a protection circuit for adjusting the soft-start voltage linearly as a function of the duration and magnitude of an overcurrent condition at the output so as to provide a scaled level of protection for said converter.
