Notes

1. Guaranteed by design, not tested.

2. MFL2828S specifiications are at 25°Tc.

3. Unit will shut down above approximately 45V but will be undamaged and

will restart when voltage drops into normal range.

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.

6. Tested on release from inhibit.

7. Shall not compromise DC performance
