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.
