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. Operation is limited below 16V (see Figure 22).
4. Indefinite short circuit protection not guaranteed above 125°C case.
5. Recovery time is measured from application of the transient to point at which
Vout is within 1% of final value.
6. Transition time ≥10 μs.
7. Tested on release from inhibit.
