notes

1. guaranteed by design, not tested.

2. To maintain tight regulation over the full input voltage range a minimum load of 2% of full load should be used on all outputs.

3. Converters meet MIL-STD-461 specification revisions for conducted emissions C-CE03 and D-/E-/F-CE-102. The actual value of input ripple

current is much less, the limit in the characteristic table is based on measurement resolution..

4. Maximum power dissipation when output is shorted.

6. Transition time >10 µs.

7. Half load to/from full load.

8. Measured from release of inhibit or input voltage step
