Notes
1. MFL2828S specifiications are at 25°Tc, contact your Interpoint repre-
sentative for more information.
2. Unit will shut down above approximately 45V but will be undamaged and
will restart when voltage drops into normal range.
3. Indefinite short circuit protection not guaranteed above 125°C case.
4. Recovery time is measured from application of the transient to point at
which Vout is within 1% of final value.
5. Transition time
≥
10 μs.
