Notes
1. The sum of the two aux outputs is not to exceed 10 watts. The maximum
load per aux output is 9 watts.
2. To maintain regulation when operating the ±Aux at full load, a minimum load
of 500 mA is required on the main.
3. Measured on each output one at a time with the other outputs at full load.
4. Indefinite short circuit protection not guaranteed above 125°C (case).
5. Response of each output as all outputs are simultaneously transitioned.
Main: 50% - 100% - 50% of main full load
Auxiliaries: 25% - 50% - 25% each, of total auxiliary full load
6. Recovery time is measured from application of the transient to point at
which Vout is within 1% of regulation.
