The low profile SMRT28 converters are manufactured in Interpoint’s fully certified and qualified MIL-PRF-38534 production facility and packaged in hermetically sealed steel cases. They are ideal for use in programs requiring high reliability, small size, and high levels of radiation hardening assurance. The SMRT28 converters are switching regulators which use a two-phase, phase shifted flyback design with a nominal switching frequency of 300 kHz. Close regulation is maintained with advanced constant frequency pulse width modulation design techniques. The SMRT28’s feed-forward compensation and discontinuous topologies provide high levels (80 dB peak) of input-to-output ripple rejection. A minimum load of 2% of full load should be used on outputs at TID of 100 kRad(Si) or greater to ensure tight regulation over the full input range. The converter should not be inhibited or operated below 19 Vin above 5x104 rad(Si) total dose. Two independent feedback loops are used to regulate the dual and triple outputs, one feedback loop regulates the two-phased single output. Each set of outputs is electrically isolated from the other and from the input. This product configuration eliminates cross regulation effects between output sets. Configurations: • Single Output: One two-phase single output • Dual Output: Two single-phase single outputs • Triple Output: One single-phase independent Main output and one single-phase dual output.

SMRT28 Rev E - 20100216 Page 1 of 19 Crane Aerospace & Electronics Power Solutions sMrt28 single, Dual and triple space Dc/Dc converters 28 VOLt Input – 35 Watt – space quaLIFIeD unDerVOltage lOCkOut The converters have an undervoltage lockout that will allow power conversion at approximately 17 volts on a rising input voltage and a conversion shut-down on a falling voltage at approximately 14.5 volts. At the highest dose rate (1011 rad(Si)/sec dose rate) there will be an upset resulting in a dip in the voltage. This is non-destructive to the unit. The converter will operate through the upset. SCreenIng InhIbIt FunCtIOn The SMRT28 Series incorporates an inhibit terminal that can be used to disable internal switching. It is not recommended to tie the Inhibit pin of an SMRT28 directly to the Inhibit pin of another converter as the SMRT28 Inhibit pin can sink current. When pulling multiple inhibit signals low a separate interface is recommended for each SMRT28. The converter is inhibited when the inhibit pin is pulled low (0.4 V). In the inhibit mode the inhibit pin current requirement is less than ~2 mA. The converter resumes normal operation when a high (≥ 2.4 V) signal or open circuit is applied to the inhibit pin. The open circuit voltage of the inhibit is 5 to 6 volts. Although open circuit is the preferred method for the enabled state, up to 10 volts may be applied to the inhibit pin. SMRT28 converters offer the following screening options: Space Prototype (O), Class H, or Class K. Radiation tolerant to Radiation Hardness Assurance (RHA) levels of “-” (O), “P”, “R” or “F”, per MIL-PRF-38534. Interpoint model numbers use an “O” in the RHA designator position to indicate the “-” (dash) Radiation Hardness Assurance level of MIL-PRF-38534, which is defined as “no RHA”. See Screening Tables 1, 2 and 3 for more information. emI The SMRT28 has a built-in EMI input filter which brings the conducted emissions into compliance with both methods of MIL-STD-461, revisions C-CE03 and D-/E-/F-CE102. SenSe SynChrOnIzatIOn The Sync Input is isolated which allows Sync Return to be tied to the primary side, secondary side, or float with respect to all inputs and outputs. Input current into this pin is limited by a series 1 k ohm resistance. Tight load regulation is maintained via wide bandwidth magnetic feedback and through the use of remote sense on single output models and one output (Output “A”) of the dual units. The sense feature can be used to adjust the output voltage by connecting a resistor between the positive sense line and the positive output. Output VOltage trIm The output voltage of each set can be trimmed from 51% to 125% of nominal (varies by model, see trim instructions on page 4). The following are “sets” of voltages in relation to trim: • Triple output models: Main output is one set, the dual outputs are another set. • Dual outputs: Each output is a “set.” One set can be trimmed using the trim pin, the other set can be trimmed (up only) using the positive sense pin. • Single: One set The SMRT28 DC/DC converters are designed to provide continuous normal operation through radiation levels associated with space missions and in tactical and strategic military environments. The converters will operate normally in radiation environments with up to 1 x 1012 neutrons per square centimeter neutron fluence, 1011 rad(Si) per second dose rate, and 3x105 rad(Si) total dose. These levels of radiation tolerance make the SMRT28 converters suitable for electronics in programs where operation in high radiation environments is required.

Up to the maximum specified auxiliary output current/power is available from either auxiliary output provided the total auxiliary output current/ power does not exceed the total current/power specified . 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. To maintain the cross regulation specification, one of the auxiliaries must always provide a minimum of 20% of the total auxiliary power used. negative Vout cross regulation is referenced to 50%/50% balanced loads (at 100% of total rated output power - full load). 5. Cross regulation is measured under the following conditions: Condition 1: +POUT = 20 - 80%,/- POUT = 80 - 20% Condition 2: - POUT = 20 - 80%, /+ POUT = 80 - 20% 6. 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. 7. Efficiency measured with all outputs at full load. 8. Maximum power dissipation when all outputs are shorted simultaneously. 9. Recovery time is measured from application of the transient to point at which VOUT is within 1% of VOUT at final value. 10. Transition time >10 µs. 11. Half load to/from full load. 12. Measured from release of inhibit or input voltage step. www.interpoint.com Page 15 of 19 SMRT28 Rev E - 20100216 Crane Aerospace & Electronics Power Solutions sMrt28 single, Dual and triple space Dc/Dc converters 28 VOLt Input – 35 Watt – space quaLIFIeD BOTTOM VIEW CASE S Seal hole: 0.135 ±0.005 (3.43 ±0.13) 2.205 max (56.01) 3x 2.075 (52.68) 1.700 (43.18) 1.500 (38.10) 1.675 (42.5) 1.300 (33.02) 1.100 (27.94) 0.900 (22.86) 0.700 (17.78) 0.500 (12.70) 3x 0.125 (3.15) 0.262 (6.65) 14 13 12 11 10 9 8 1 2 3 4 5 6 x 0.135 (3.43) dia.
