ꢀotes:
(All temperatures in tables and notes refer to case temperature, TC.)
1. ꢃꢀꢁrꢁnteed ꢆꢄ design, not tested.
2. The sum of the two Aux outputs is not to exceed 10 watts. The maximum load
per Aux output is 7.5 watts.
3. To maintain regulation when operating the ±Aux at full load, a minimum load of
300 mA is required on the main output. For Aux loads less than full load, a lower
load (<300 mA) on the main output will maintain regulation.
6. 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
7.Recovery time is measured from application of the transient to point at which
Vout is within 1% of regulation.
8. Tested on release from inhibit.
4. Measured on each output one at a time with the other outputs at full load.
5. Indefinite short circuit protection not guaranteed above 125°C (case).
