Notes
1. Guaranteed by design, not tested.
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.
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.
5. Load fault is a short circuit (<50 mΩ). Recovery is into a resistive load.
4. Cross regulation occurs between the two auxiliaries and is measured on –aux. +5 is held 6. Load step transition ≥ 10 μs. Recovery = time to settle to within 1% of Vout final value.
constant at 2.0 A. Cross regulation is specified for two conditions:
7. Input step transition ≥ 10 μs. Recovery = time to settle to within 1% of Vout final value.
