The low profile SMRT converters are manufactured in our 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 hardness assurance. The SMRT 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 SMRT's feed-forward compensation and discontinuous topologies provide high levels (60 dB peak) of input-to-output ripple rejection.

Crane Aerospace & Electronics Power Solutions SMRT Single, Dual and Triple Space DC-DC Converters 19-56 Volt input - 35 Watt - Space qualified Undervoltage Lockout Screening 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. Inhibit Function The SMRT Series incorporates an inhibit terminal that can be used to disable internal switching. It is not recommended to tie the Inhibit pin of an SMRT directly to the Inhibit pin of another converter as the SMRT Inhibit pin can sink current. When pulling multiple inhibit signals low, a separate interface is recommended for each SMRT. 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 an open circuit is applied to the Inhibit pin or the Inhibit pin is open (unconnected). The open circuit voltage of the Inhibit pin is 5 to 6 volts. To enable the converter use an open collector on the Inhibit pin or leave it unconnected. Synchronization The Sync Input pin is isolated which allows Sync Return pin 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. Radiation Tolerance The SMRT 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 100 krad(Si) total dose. The converter will not exhibit low dose rate (LDR) effects at 10 mrad(Si)/sec dose rate up to a TID of 100 krad. These levels of radiation tolerance make the SMRT converters suitable for electronics in programs where operation in high radiation environments is required. SMRT 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" or "R", 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 Table 27 and Table 28 for more information. EMI The SMRT 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. Electrostatic Discharge (ESD) Sensitivity Per MIL-PRF-38534, the SMRT Series converters are rated to ESD class 3B defined as sensitivity equal to, or greater than, 8000 volts. Sense Tight load regulation is maintained via wide bandwidth magnetic feedback and through the use of remote sense on single output models and Vout A on dual output models. The sense pin function allows a remote connection for the voltage regulation circuit to compensate for voltage drops between the converter and the point of use. Note that if the sense pins are connected but the output voltage pins are not, the converter may be damaged. The maximum voltage drop from the output to the sense pin is shown in Table 1 below. Nominal Output Voltage (V) 1 Max Voltage drop (V) Max Voltage at converter (Vmax) 1 3.3 2 0.58 5 1.0 6.0 1.9 10.58 12 2.68 14.68 15 3.36 18.36 Table 1: Maximum Voltage Drop Using Remote Sense Single and Dual Models only 8.7 2 3.88 Notes for Table 1 1.

Trim can be achieved using the provided trim pin or in some cases the sense pin. The preferred method is the use of the trim pin. Every converter in the SMRT family provides a trim pin that allows at least one output to be adjusted. See Table 3 and Table 4 for maximum adjust range for each output voltage. The single output models provide a trim pin and remote sense. The dual output models allow remote sense on Vout A and have a trim pin on the Vout B. The triples have a trim pin on the Vout A (main)and a single trim pin for both Vout B auxiliaries. Voltage Adjust Feature Trim Pin (Formulas 1 and 2) Sense Pin (Formula 3) For outputs without a trim pin, the output at the converter can be adjusted up by adding resistance in series with the sense pin. See Table 2 for a summary of trim features and see below for details on the trim features. See Formula 1 for trimming down when using a trim pin, Formula 2 for trimming up when using a trim pin and Formula 3 when trimming up using Sense A pin on a dual output model. NOTE: Do not exceed maximum current rating when trimming down. NOTE: Do not exceed maximum power rating when trimming up.

NOTES: For triple output models on Table 14 through Table 18. 1. Guaranteed by qualification test and/or analysis. Not an in-line test. 2. 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 specified regulation a 4% minimum load is required above 28 volts input and 5% minimum at or above 50 volts. The minimum load requirement applies to 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 s. 11. Half load to/from full load. 12. The Step Load specification for the negative auxiliary output is guaranteed by qualification test. It is not an in-line test. 13. Measured from release of inhibit or input voltage step. 14.

Notes: For triple output models on Table 22 through Table 26. 1. Guaranteed by qualification test and/or analysis. Not an in-line test. 2. 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 specified regulation a 4% minimum load is required above 28 volts input and 5% minimum at or above 50 volts. The minimum load requirement applies to 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 s. 11. Half load to/from full load. 12. The Step Load specification for the negative auxiliary output is guaranteed by qualification test. It is not an in-line test. 13. Measured from release of inhibit or input voltage step. 14.
