notes

1. guaranteed by design, not tested.

2. The specified maximum current/power is available from each output.

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

4. 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..

5. Maximum power dissipation when output is shorted.

6. Recovery time is measured from application of the transient to point at which V

OUT

is within 1% of V

OUT

at final value.

7. Transition time >10 µs.

8. Half load to/from full load.

9. Measured from release of inhibit or input voltage step
