Electrical Characteristics: 25°C Tc, 28 VDC Vin, 100% load, free run, unless otherwise specified.
Notes
1. Guaranteed, not tested.
2. Tc = –55°C to +125°C.
3. Up to 90% of the total output current/power is available from either output
providing the positive output is carrying at least 10% of the total output
power.
4. Operation is limited below 16 V (see Figure 22).
5. Effect on negative Vout from 50%/50% loads to 80%/20% or 20%/80%
loads.
6. Effect on negative Vout from 50%/50% loads to 90%/10% or 10%/90%
loads.
7. Indefinite short circuit protection not guaranteed above 125°C case.
8. Recovery time is measured from application of the transient to point at
which Vout is within 1% of final value.
9. Transition time ≥ 10 μs.
10. Tested on release from inhibit.
