Notes

1. Unit will shut down above approximately 425V but will be undamaged

and will restart when voltage drops into normal range.

2. Indefinite short circuit protection not guaranteed above 100°C case.

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

which Vout is within 1% of final value.
