Notes:

1. Guaranteed by design, not tested.

2. Lin = 2 µH.

3. Maximum duration of short circuit: 25°C-– 90 seconds, 150°C

– 5 seconds.

4. Load fault is a short circuit (<50 mohms). Recovery is into

resistive full load.

5. Max. spec indicates 80% of the converter’s total power, avail-

able from either output providing the other output carries a

minimum of 20% of the total load.
