Notes

1. Specified at 50% of full load.

2. Lin = 2 μH

3. Max. duration of short circuit: 25°C– 90 seconds; 125°C – 30 seconds.

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

5. Input step transition ≥ 10 μs.Recovery is time to settle to within 1% of Vout

final value.

Electrical Characteristics: 25°C Tc, 28 VDC Vin, 100% load, unless otherwise specified.
