They operate over the full military temperature range of -55C to +125C with up to 84% efficiency (up to 73% efficiency triple models). SMTR converters are packaged in hermetically sealed metal enclosures, making them ideal for use in military, aerospace and other high reliability applications. Screening SMTR converters offer screening options to Space Prototype (O), Class H, or Class K. Radiation tolerant to Radiation Hardness Assurance (RHA) levels of "-" (O), "P," or "R," per MIL-STD38534. 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 "Class H and K, MIL-PRF-38534 Screening" tables for more information. SMTR converters have internal input filter that help reduce the need for external components in normal operation. For systems that require compliance with MIL-STD-461C's CE03 standard, Interpoint offers filter/transient suppression modules (including the SFMC-461 and SFCS28-461), which will result in compliance. For the lowest noise performance, connection of the case to input common is recommended. The connection can be hard-wired or AC coupled with a small ceramic bypass capacitor. Indefinite short circuit protection and overload protection are provided by a constant current-limit feature. This protective system senses current in the converter's secondary stage and limits it to approximately 125% of the maximum rated output current. Synchronization converter DeSign The SMTR converters are constant frequency, pulse-width modulated switching regulators which use a quasi-square wave, single ended, forward converter design. Tight load regulation is maintained by using a wide bandwidth magnetic feedback and, on single output models, through use of remote sense. On dual output models, the positive output is independently regulated and the negative output is cross regulated through the use of tightlycoupled magnetics. The SMTR Triple Series DC/DC converter's design includes individual regulators on the auxiliary outputs which provide for no cross regulation error when a minimum 300 mA load is maintained on the main (+5) output. Crane Aerospace & Electronics Electronics group (Interpoint Brand) POBox97005*RedmondWA98073-9705 425.882.3100*power@crane-eg.com www.interpoint.com Synchronizing the converter with the system clock allows the designer to confine switching noise to clock transitions, minimizing interference and reducing the need for filtering. In sync mode, the converter will run at any frequency between 500 kHz and 675 kHz. The sync control operates with an active high at any duty cycle between 40% and 60%. The sync pin should be connected to input common pin when not in use.

Page 1 of 21 Crane Aerospace & Electronics Power Solutions SMTR Single, Dual and Triple DC/DC Converters 28 VOlT INPuT - 30 WaTT - PENDINg REVISION F RElEaSE WiDe voltage range SMTR converters are designed to provide full power operation over a full 16 to 40 VDC voltage range. Operation below 16 volts, including MIL-STD-704D emergency power conditions is possible with derated power. inhibit Function improveD Dynamic reSponSe The SMTR Series feed-forward compensation system provides excellent dynamic response and noise rejection. Audio rejection is typically 50 dB (for Triple output models). The min. to max. step line transient response is typically less than 4%. SMTR converters provide an inhibit terminal that can be used to disable internal switching, resulting in no output and very low quiescent input current. The converter is inhibited when an active low(0.8V)isappliedtotheinhibitpin.Theunitisenabledwhen the pin, which is internally connected to a pull-up resistor, is left unconnected or is connected to an open-collector gate. The open circuit output voltage associated with the inhibit pin is 9 to 11 VDC. In the inhibit mode, a maximum of 8 mA must be sunk from the inhibit pin.

CAUTIOn: The converter will be permanently damaged if the positive remote sense (pin 6) is shorted to ground. Damage may also result if the output common or positive output is disconnected from the load with the remote sense leads connected to the load. www.interpoint.com Page 2 of 21 Rev F - 20090324 - Pending Revision F Release Crane Aerospace & Electronics Power Solutions SMTR Single, Dual and Triple DC/DC Converters 28 VOlT INPuT - 30 WaTT - PENDINg REVISION F RElEaSE OPERaTINg CONDITIONS aND ChaRaCTERISTICS Input Voltage Range * 16 to 40 VDC continuous * 50 V for 50 msec transient audio Rejection * 40 dB typ (50 dB typ, triple output) Output Power * Up to 30 watts depending on model Conversion Frequency * Free run 550 min, 600 typ, 650 max kHz * External sync 500 to 675 kHz lead Soldering Temperature (10 sec per pin) * 300C Storage Temperature Range (Case) * -65C to +135C Case Operating Temperature (Tc) * -55C to +125C full power * -55C to +135C absolute SyNC aND INhIbIT Derating Output Power/Current * Linearly from 100% at 125C to 0% at 135C Output Voltage Temperature Coefficient * 100 ppm/C typical single and dual outputs * 200 ppm/C main, 300 ppm/C aux triple output Input to Output Capacitance * 50 pF typ (100 pF typ triple outputs) Current limit * 125% of full load typical Sync *Input frequency 500 to 675 kHz * Duty cycle 40% min, 60% max * Active low 0.8 V max * Active high 4.5 V min, 5 V max * Referenced to input common * If not used, connect to input common Inhibit * Active low (output disabled) oltage0.8V V Inhibit pin source current 8.0 mA max Referenced to input common * Active high (output enabled) Open collector or unconnected If not used, leave unconnected Inhibit pin voltage, 9 to 11 V Isolation * 100 megohm minimum at 500 VDC * Any pin to case, except case pin MEChaNICal aND ENVIRONMENTal Size (maximum) * Single and dual output non-flanged: 2.125 x 1.115 x 0.400 inches (53.98 x 28.58 x 10.16 mm) See case H2 for dimensions.
