Notes:
1. Specified at 50% load.
ages of total output power: +Po = 20% and
–Po = 80% to +Po=80% and –Po=20%
6. Lin = 2 μH.
2. Max. spec indicates 80% of the converter’s total available power. This 80%
is available from either output.
3. Specification applies to both + and –Vout.
7. Max. duration of short circuit: 25°C – 90 seconds; 125°C – 30 seconds.
8. Load fault is a short circuit (<50 mohms). Recovery into resistive full load.
9. Input step transition ≥ 10 μs.Recovery is time to settle to within 1% of Vout
final value.
4. Although no minimum load is required, at no load the output voltage may
increase up to 15%.
5. Cross regulation is specified as the effect on –Vout for the following percent
