Notes:
1. Guaranteed by design, not tested.
2. Specified at 50% total P_out.
3. Lin = 2 μH.
4. Maximum duration of short circuit: 25°C-– 90 seconds, 125°C – 30 seconds.
5. Load fault is a short circuit (<50 mohms). Recovery is into resistive full load.
6. Transition ≥ 10 μs. Recovery = time to settle to within 1% of Vout final value.
7. Max. spec indicates 80% of the converter’s total power, available from either
output.
