Notes 1. Guaranteed by characterization test and/or analysis. Not a production test. 2. Up to 70% of the total output power is available from either output providing the opposite output is simultaneously carrying 30% of the total output power. 3. Recommended minimum load is 20% total load (sum of both outputs). 4. Effect on –Vout for the following conditions: +Po = 30% to 70%; - Po = 70% to 30% 5. Short circuit measured with 1% 10 milliohm resistive load. 6. Indefinite short circuit protection not guaranteed above 125°C (case) 7. Recovery and startup times are measured from application of the transient or change in condition to the point at which VOUT is within 1% of final value. CL = 0. 8. Response of either output with the opposite output held at half of the total output power. 9. Step load transition time 10 µs ±1 µs. 10. Step line transition time >100 µs. 11. Tested on release from inhibit. 12. Each output.
