Notes

1. guaranteed by characterization test and/or analysis. Not a production test.

2. Converter will shut down above approximately 45 volts but will be

undamaged and will restart when voltage drops into normal range.

3. Recovery time is measured from application of the transient to point at

which VOuT is within 1% of final value.

4. Tested on release from inhibit.

5. No effect on dc performance.
