Notes
1. Up to 4 watts, 80% of the total output power is available from either output
providing the opposite output is simultaneously carrying 20% of the total
output power. Each output must carry a minimum of 20% of the total output
power in order to maintain regulation on the negative output.
2. Applies to both +Vout and –Vout
3. Cross regulation is specified for the following percentages of total output
power: +PO = 20% and –PO = 80% to +PO =80% and –PO = 20%
4. Indefinite short circuit protection not guaranteed above 125°C (case).
5. Load transient transition time is >10 µs.
6. Response of either output when the load for each output is simultaneously
transitioned from 25% to 50% to 25% of total output power (5 watts).
7. Recovery time is measured from application of the transient to the point at
which Vout is within regulation.
8. Input step transition time is >10µs.
