MODELS
DESCRIPTION
The SMTR SeriesTM of 28 volt DC/DC converters offers up to 30 watts of output power from single, dual or triple output configurations. 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.

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.

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.

notes for Remote Sense and Trim 1.Whentrimmingoutputvoltageand/orremotesensing,the total output voltage increase must be less than 0.6 volts at the converters pins to maintain specified performance. 2. If neither voltage trim nor remote sense will be used, connect pin 3 to pin 4 and pin 5 to pin 6 or the output voltage will increase by 1.2 volts. 3. 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.

Operation is limited below 16 V (see Figure 22). 5. Effect on the negative output under the following conditions: +Pout 20% to 80%; -Pout 80% to 20%
6. Effect on the negative output under the following conditions: +Pout 50%; -Pout 10% to 50% 7. Tested with 6800 pF ceramic bypass capacitors connected externally from input common to case. 8. Indefinite short circuit protection not guaranteed above 125C case temperature. 9. Recovery time is measured from application of the transient to point at which Vout is within 1% of final value. 10.Transitiontime10s.

Notes: 1. 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". 2. Space Prototype (O), non-QML, products do not meet all of the requirements of MIL-PRF-38534. 3. Redmond site, Interpoint, has a Radiation Hardness assurance plan on file with DSCC.
