Notes
1. Guaꢅaꢁꢆꢂꢂꢃ by ꢃꢂꢇꢀgꢁ, ꢁꢄꢆ ꢆꢂꢇꢆꢂꢃ.
4. Transition time 100 µs ±20%.
5. Tested on release from inhibit.
6. Shall not compromise DC performance.
2. Unit will shut down above approximately 45V but will be undam-
aged and will restart when voltage drops into normal range.
3. Recovery time is measured from application of the transient to the
point at which Vout is within 1% of final value.
