notes

1. guaranteed by characterization test and/or analysis. not a production test.

2. The inhibited input current is tested with <0.8 volts on the inhibit.

3. For RHA L, 50 krad converters, the pre-radiation spec for Iin Inhibit is 7

mA max.

4. Tested with a 2 µH external input inductor.

5. Indefinite short circuit protection not guaranteed above 125°C (case).

6. Recovery time is measured from application of the transient to point at

which VOuT is within 1% of VOuT at final value.
