DESCRIPTION
The Interpoint™ 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.
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 tightly-
coupled magnetics. The triple output dc-dc converter’s
Screening
design includes individual regulators on the auxiliary outputs
SMTR converters offer screening options to Space Prototype (O), which provide for no cross regulation error when a minimum
Class H, or Class K. Radiation tolerant to Radiation Hardness
Assurance (RHA) levels of “-” (O), “P,” or “R,” per MIL-STD-
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 11: Element Evaluation” on page 19 and
“Table 12: Environmental Screening and RHA Levels” on page
20 for more information.
300 mA load is maintained on the main (+5 V) output.
SMTR converters have an internal input filter that helps reduce
the need for external components in normal operation. Use our
SFMC EMI input filter to meet the requirements of MIL-STD-
461C’s CE03. 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 140% of the maximum rated
output current.

28 Volt input – 30 Watt
Synchronization
improveD Dynamic reSponSe
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.
The SMTR Series feed-forward compensation system provides
excellent dynamic response and noise rejection. Audio rejection
is typically 40 dB (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 voltage and very
low quiescent input current. The converter is inhibited when the
inhibit pin is pulled below 0.8 V and enabled when its inhibit pin
is left floating. An external inhibit interface should be capable of
pulling the converter’s inhibit pin below 0.8 V while sinking the
maximum inhibit current and also allowing the inhibit pin to float
high to enable the converter. A voltage should not be applied to
the inhibit pin. The open circuit voltage present on the inhibit pin
is 9 to 11 V.
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. Refer to the low line dropout
graphs (“Figure 23” on page 13, “Figure 31” on page 14 and
“Figure 32” on page 14) for details.

Notes for Remote Sense and Trim
Trim Formulas Vout = desired output voltage;
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. Do not exceed maximum power.
R
= trim resistor
T
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

also result if the output common or positive output is disconnected
from the load with the remote sense leads connected to the load.
4. When using remote sense for voltage compensation or when using

Notes:
1. Guaranteed by qualification test and/or analysis. Not an in-line test.
2. The specified max current is available from either output.
6. Effect on the negative output under the following conditions:
+POUT 50%; –POUT 10% to 50%. See “Figure 22” on page 13.
3. Up to 90% of the total output current/power is available from either output
providing the positive output is carrying at least 10% of the total output
power.
4. Operation is limited below 16 V (see “Figure 23” on page 13).
5. Effect on the negative output under the following conditions:
+POUT 20% to 80%; –POUT 80% to 20%.
7. Tested with 6800 pF ceramic bypass capacitor connected externally from
input common to case.
8. Indefinite short circuit protection not guaranteed above 125°C case
temperature.
9. Recovery time is measured from application of the transient to point at
which VOUT is within 1% of final value.
10. Tested on release from inhibit.

Notes:
1. Guaranteed by qualification test and/or analysis. Not an in-line test.
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.
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.
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).

Notes:
1. Our Redmond facility has a DLA approved RHA plan for Interpoint power
products. Our SMD products with RHA “P” or “R” code meet DLA requirements.
2. “OO” prototypes are non-QML products and may not meet all of the requirements
of MIL-PRF-38534. “O” in the RHA designator position in Interpoint model
numbers indicates DLA RHA “-” defined as no RHA.
3. All processes are QML qualified and performed by certified operators.
4. Not required by DLA but performed to assure product quality.
5. Burn-in temperature designed to bring the case temperature to +125°C minimum.
Burn-in is a powered test.
