Notes

1. Guaranteed by design, not tested.

2. The sum of the 12 volt auxiliary output currents may not exceed 416 mA.

The sum of the 15 volt auxiliary output currents may not exceed 333 mA.

3. The sum of the auxiliary output power may not exceed 5 watts.

4. Cross regulation occurs between the two auxiliaries and is measured on –aux. +5 is held

constant at 2.0 A. Cross regulation is specified for two conditions:

A. Positive aux. = 2.5 W; -(50%) negative aux. = 2.5 W to 0.5 W (50% to 10%).

B. From +Po = 70% and -Po = 30% to + Po = 30% and -Po =70%.

Above conditions are referenced to 50%/50% balanced loads.

5. Load fault is a short circuit (<50 mΩ). Recovery is into a resistive load.

6. Load step transition ≥ 10 μs. Recovery = time to settle to within 1% of Vout final value.

7. Input step transition ≥ 10 μs. Recovery = time to settle to within 1% of Vout final value.
