Up to 13.5 watts, 90% (9.6W, 80% for 2805D) of the total output power is available from either output providing the opposite output is simultaneously carrying 10% (20% for 2805D) of the total output power. Each output must carry a minimum of 10% (20% for 2805D) of the total output power in order to maintain regulation on the negative output. 2. Effect on –Vout for the following conditions: +Po = 50% to 10% and –Po = 50% +Po = 50% and –Po = 50% to 10% 3. Indefinite short circuit protection not guaranteed above 125°C (case) 4. Recovery time is measured from application of the transient to point at which Vout is within regulation. 5. Response of either output with the opposite output held at half of the total output power. 6. Input step transition time >10 µs. 7. Input step transition time <100 µs. |
