7 / 19 page  Electrical Characteristics: -55°C to +125°C TC, 28 VDC Vin, 100% load, unless otherwise specified. 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. 5. Recovery time is measured from application of the transient to point at which VOUT is within 1% of VOUT at final value. 6. Transition time >10 µs. 7. Half load to/from full load. 8. Measured from release of inhibit or input voltage step SIngLE OUTPUT MODELS SMRT283R3S SMRT2805S SMRT288R7S unItS parameter COnDItIOnS MIn TYP MAX MIn TYP MAX MIn TYP MAX Output VOltage 3.23 3.30 3.37 4.90 5.00 5.10 8.52 8.70 8.87 VDC Output Current 2 0 — 6.97 0 — 6.0 0 — 4.0 A Output pOwer 2 VIn = 19 tO 56 VDC 0 — 23 0 — 30 0 — 35 W Output rIpple 10 khz - 20 mhz — — 280 — — 200 — — 200 mV p-p lIne regulatIOn 2 VIn = 19, 50 VDC — 5 30 — 5 30 — 5 30 mV lOaD regulatIOn — 5 40 — 5 40 — 5 80 mV VIn = 19, 50 — — 90 — — 70 — — 80 tOtal regulatIOn 1 VOut all COnDItIOnS OF lIne, lOaD, agIng, temp anD raDIatIOn 3.0 — 3.6 4.7 — 5.3 8.3 — 9.1 VDC Input VOltage COntInuOuS 19 28 56 19 28 56 19 28 56 VDC tranSIent 1 100 ms 0 — 80 0 — 80 0 — 80 V Input Current InhIbIteD — — 50 — — 50 — — 50 mA nO lOaD — — 110 — — 110 — — 115 Input rIpple Current 3 10 kHz - 20 MHz — 10 50 — 10 50 — 10 50 mA p-p eFFICIenCy 60 — — 66 — — 72 — — % lOaD Fault 4, 5 POWERDISSIPATION — — 31 — — 28 — — 25 W reCOVery 1 — — 25 — — 25 — — 25 ms Step lOaD reSpOnSe 5, 6, 7 tranSIent — — ±450 — — ±450 — — ±450 mV pk reCOVery — — 3 — — 3 — — 4 ms Step lIne reSpOnSe 1, 5, 6 19 - 50 - 19 VIn tranSIent — — ±500 — — ±500 — — ±500 mV pk reCOVery — — 4 — — 4 — — 4 ms Start-up 8 Delay nO lOaD anD Full — — 35 — — 25 — — 60 ms OVerShOOt — — 50 — — 50 — — 95 mV pk CapaCItIVe lOaD 1 tC = 25°C unCOnDItIOnally Stable, Start-up Delay InCreaSeD — — 5000 — — 5000 — — 5000 µF Crane Aerospace & Electronics Power Solutions www.interpoint.com Page 7 of 19 sMrt28 single, Dual and triple space Dc/Dc converters 28 VOLt Input – 35 Watt – space quaLIFIeD SMRT28 Rev E - 20100216 |
