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.
3. Effect on negative Vout from 50%/50% loads to 70%/30% or
30%/70% loads.
4. Effect on negative Vout from 50%/50% loads to 50% then 10% load on negative
Vout.
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.
7. Transition time > 10 µS.
8. Tested on release from inhibit.
9. Shall not compromise DC performance.
