Notes
1. Guaranteed by design, not tested.
2. MFL283R3S current and power maximum are at 25°C only.
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
