Notes:
1. Guaranteed by design, not tested.
2. Up to 70% of the total output power is available from either output
providing the opposite output is simultaneously carrying 30% of the
total power.
5. Unit will shut down above approximately 45V 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.
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.
7. Transition time ≥ 10 μs.
8. Parallel/current share operation is not characterized for dual output
models.
