description

The Interpoint® SMR T Series™ of dc-dc converters of fers up to watts of power in a radiatio n tolerant design. The low profile SMR T 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 requiri ng high reliabilit small size, and high levels of radiation hardne ss assurance. The SMR T 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 SMR T’s feed-forward compensation and discontinuous topologies provide high levels of input-to-output ripple rejection. See Figure on page 29, Figure and Figure on page and Figure and Figure on page 36. T wo independen t 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 ef fects between output sets.

The converters have an undervoltage lockout that will allow power conversio n at approximat ely volts on a rising input voltage and a conversion shut-down on a falling voltage at approximately 14.5 volts. InhIbIt FunctIOn The SMR T Series incorporates an inhibit terminal that can be used to disable internal switching. It is not recommended to tie the Inhibit pin of an SMR T directly to the Inhibit pin of another converter as the SMR T Inhibit pin can sink current. When pulling multiple inhibit signals low a separate interface is recommended for each SMR The converter is inhibited when the Inhibit pin is pulled low (0.4 V). In the inhib it mode the inhibit pin current requirement is less than 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 to volts. T o enab le 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 k ohm resistance. radIatIOn tOlerance The SMR T dc-dc converters are designed to provide continuous normal operation through radiati on levels associated with space missions and in tactical and strategic military environments. The RHA level R converters will operate normally in radiation environments with up to 100 krad(Si) total dose and will not exhibit low dose rate (LDR) ef fects at mrad(Si)/sec dose rate up to a TID of 100 krad. These levels of radiation tolerance make the SMR T converters suitable for electronics in programs where operation in high radiation environ ments is require ScreenIng SMRT converters of fer screening options to space prototype (O), Class H or K and radiation hardness assurance (RHA) levels P - krad(Si), L - krad(Si) or R 100 krad(Si). Single event ef fects (SEE) LET performance to MeV cm2/mg. See T able 27 and T able for more information. eMI The SMR T 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 SMR T Series converters are rated to ESD class 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 T able below NOMINAL O UTPUT V OLTAGE (V) 1 MAx V OLTAGE DROP (V) M A x V OLTAGE AT CONVERTER (VMAx) 1 3.3 2 0.58 3.88 5 1.0 6.0 8.7 2 1.9 10.58 12 2.68 14.68 15 3.36 18.36 Notes for T able 1 Do not exceed maximum voltage.

TRIM D OWN USING TRIM PIN , ALL M ODELS To trim the output voltage lower than the nominal set point, connect RTRIM as shown in Figure 1. The value of RTRIM is calculated by the following equation: FOrMula 1: trIM dOwn uSIng trIM pIn RTRIM = K ( VOUT – VMIN) / (VNOM – VOUT ) Where: K Multiplication constant from T able VOUT = Desired output voltage (must be greater than VMIN) VMIN = Minimum output voltage from T able 3 VNOM = Nominal set point voltage of the converter NOTE: Do not exceed maximum current rating when trimming down.

TRIM UP USING S ENSE A P IN ON D UAL M ODELS O NLy Trim Up VOUT A In addition to remote sensing, the Sense A pin may be used to increase the regulated output voltage at the VOUT A pin. This is accomplished by attaching a resistor (RADJUST) between the Sense A pin (pin and the VOUT A pin (pin 1 1). The value of RADJUST is calculated by the following equation: FOrMula 3: trIM up uSIng SenSe a pIn RADJUST = 240 (Vout – Vnom ) / (K + (Vmax – Vout)) Where: VOUT = Desired output voltage (must be less than VMAx) VNOM = Nominal set point voltage of the converter VMAx = Maximum achievable output voltage NOTE: Do not exceed maximum power rating when trimming up.

Notes for triple output models on T able 14 through T able 18. Guaranteed by characterization test and/or analysis. Not a production test. 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. Line regulation is tested at full load. However to maintain regulation above volts input, a minimum load is required of at volts input increasing linearly to at volts in. Load percentage applies to the main output and also to the sum of the auxiliaries. T o maintain the cross regulation specification, one of the auxiliaries must always provide a minimum of 20% of the total auxiliary power used. Negative V out cross regulation is referenced to 50%/50% balanced loads (at 100% of total rated output power full load). Cross regulation is measured under the following conditions: Condition Condition 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. Ef ficiency measure d with all outputs at full load. Maximum power dissipation when all outputs are shorted simultaneously Recovery time is measured from applic ation of the transient to point at which VOUT is within 1% of VOUT at final value 10. T ransition time >10 µs. 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.

Notes for triple output models on T able 22 through T able 26. Guaranteed by characterization test and/or analysis. Not a production test. 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. Line regulation is tested at full load. However to maintain regulation above volts input, a minimum load is required of at volts input increasing linearly to at volts in. Load percentage applies to the main output and also to the sum of the auxiliaries. T o maintain the cross regulation specification, one of the auxiliaries must always provide a minimum of 20% of the total auxiliary power used. Negative V out cross regulation is referenced to 50%/50% balanced loads (at 100% of total rated output power full load). Cross regulation is measured under the following conditions: Condition Condition 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. Ef ficiency measure d with all outputs at full load. Maximum power dissipation when all outputs are shorted simultaneously Recovery time is measured from applic ation of the transient to point at which VOUT is within 1% of VOUT at final value 10. T ransition time >10 µs. 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. Applies to each auxiliary Electrical Charac teristics: -55°C to +125°C case, 50 V in, 100% load, free run, unless otherwise specified.
