DESCRIPTION
The SMTR Series™ 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
-55°C to +125°C 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.
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.

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
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.

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.
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%.
Inhibit Function
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) is applied to the inhibit pin. The unit is enabled when
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.When trimming output voltage and/or remote sensing, 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.

Notes:
(All temperatures in tables and notes refer to case temperature, TC.)
1.Guaranteed by design, not tested.
2.The sum of the two Aux outputs is not to exceed 10 watts. The maximum load
per Aux output is 7.5 watts.
3.To maintain regulation when operating the ±Aux at full load, a minimum load of
300 mA is required on the main output. For Aux loads less than full load, a lower
load (<300 mA) on the main output will maintain regulation.
4.Measured on each output one at a time with the other outputs at full load.
5.Indefinite short circuit protection not guaranteed above 125°C (case).
www.interpoint.com
6.Response of each output as all outputs are simultaneously transitioned.
Main: 50% - 100% - 50% of main full load
Auxiliaries: 25% - 50% - 25% each, of total auxiliary full load
7.Recovery time is measured from application of the transient to point at which
Vout is within 1% of regulation.
8. Tested on release from inhibit.
