Notes

1. Guaranteed by design, not tested.

2. Maximum power dissipation when output is shorted.

3. Measured from release of inhibit or input voltage step.

4. Minimum value pre-load on all outputs of 2% of full load should be used on all outputs at TID of 100k rads(Si) and greater to ensure tight regulation

over full input voltage range.

5. Half load to/from full load; Transition time

≥

10

μs.

6. Converter should not be inhibited or operated below 19 Vin above 5x10

4

rads (Si) total dose.

7. If 3.3S model is trimmed to the high end of its range, then minimum Vin = 22 V.

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

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