Electrical Characteristics: 25°C Tc, 28 VDC Vin, 100% load, unless otherwise specified.

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.
