Notes
1. Guaranteed by characterization test and/or analysis. Not a production test.
2. Up to 70% of the total output power/current is available from either output
provided the opposite output is carrying 30% of the power/current in use.
3. Effect on negative Vout from 50%/50% loads to 30%/70% or 70%/30% loads.
4. Effect on negative Vout from 50%/50% loads to 10% then 50% load on
negative Vout
5. Converter will shut down above approximately 45 volts but will be undamaged
and will restart when voltage drops into normal range.
6. Recovery time is measured from application of the transient to point at which
Vout is within 1% of final value.
7. Tested on release from inhibit.
8. No affect on dc  performance.
9. Applies to each output.
