Two independent 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 effects between output sets.
The SMRT28 Series™ of DC/DC converters offers up to 35
watts of power in a radiation tolerant design. The low profile
SMRT28 converters are manufactured in Interpoint’s fully
certified and qualified MIL-PRF-38534 production facility and
packaged in hermetically sealed steel cases. They are ideal for
use in programs requiring high reliability, small size, and high
levels of radiation hardening assurance.
Configurations:
•ꢀSingleꢀOutput:ꢀOneꢀtwo-phaseꢀsingleꢀoutput
•ꢀDualꢀOutput:ꢀTwoꢀsingle-phaseꢀsingleꢀoutputs
•ꢀTripleꢀOutput:ꢀOneꢀsingle-phaseꢀindependentꢀ
Main output and one single-phase dual output.
(± Auxiliary output)
The SMRT28 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 SMRT28’s feed-forward compensation and
discontinuous topologies provide high levels (80 dB peak) of
input-to-output ripple rejection.

At the highest dose rate (1011 rad(Si)/sec dose rate) there will be
an upset resulting in a dip in the voltage. This is non-destructive
to the unit. The converter will operate through the upset.
un D e r V O l t a g e lO C k O u t
The converters have an undervoltage lockout that will allow
power conversion at approximately 17 volts on a rising input
voltage and a conversion shut-down on a falling voltage at
approximately 14.5 volts.
SC r e e n I n g
SMRT28 converters offer the following screening options:
Space Prototype (O), Class H, or Class K. Radiation tolerant to
Radiation Hardness Assurance (RHA) levels of “-” (O), “P”, “R” or
“F”, per MIL-PRF-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 Screening Tables 1, 2 and 3 for more information.
In h I b I t Fu n C t I O n
The SMRT28 Series incorporates an inhibit terminal that can
be used to disable internal switching. It is not recommended
to tie the Inhibit pin of an SMRT28 directly to the Inhibit pin of
another converter as the SMRT28 Inhibit pin can sink current.
Whenꢀpullingꢀmultipleꢀinhibitꢀsignalsꢀlowꢀaꢀseparateꢀinterfaceꢀ
is recommended for each SMRT28. The converter is inhibited
when the inhibit pin is pulled low (0.4 V). In the inhibit mode the
inhibit pin current requirement is less than ~2 mA. The converter
resumesꢀnormalꢀoperationꢀwhenꢀaꢀhighꢀ(≥ꢀ2.4ꢀV)ꢀsignalꢀorꢀopenꢀ
circuit is applied to the inhibit pin. The open circuit voltage of
the inhibit is 5 to 6 volts. Although open circuit is the preferred
method for the enabled state, up to 10 volts may be applied to
the inhibit pin.
emI
The SMRT28 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.
Se n S e
Tight load regulation is maintained via wide bandwidth magnetic
feedback and through the use of remote sense on single output
models and one output (Output “A”) of the dual units. The sense
feature can be used to adjust the output voltage by connecting a
resistor between the positive sense line and the positive output.
Sy n C h r O n I z a t I O n
The Sync Input is isolated which allows Sync Return 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 1 k
ohm resistance.

The output voltage of each set can be trimmed from 51% to

ra D I a t I O n tO l e r a n C e
The SMRT28 DC/DC converters are designed to provide
continuous normal operation through radiation levels associated
with space missions and in tactical and strategic military
environments. The converters will operate normally in radiation
environments with up to 1 x 1012 neutrons per square centimeter
neutron fluence, 1011 rad(Si) per second dose rate, and 3x105
rad(Si) total dose.
ꢀote: RADJUST should be connected
between Sense A (pin 8) and Vout A (pin 11).
These levels of radiation tolerance make the SMRT28 converters
suitable for electronics in programs where operation in high
radiation environments is required.

SMRT28 is the only
available selection
3r312, 3r315,
507, 512, 515
ꢀotes:
1. Output Voltage: An R indicates a decimal point. 3R3 is 3.3 volts out. The 3R3 output voltage is only available in single and triple output models. The 3R312
and 3R315 triple output converters are +3.3 volt main and ±12 or ±15 volt auxiliaries. 512 and 515 triple output converters are +5 volt main and ±12 or ±15 volt
auxiliaries.
2. ꢀumber of Outputs: S is a single output, D is a dual output, and T is a triple output
3. Screening: A screening level of O is a Space Prototype and is only used with RHA O. See Screening Tables 2 and 3 for more information.
4. RHA: 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.” RHA O is only available with Screening level O. See Screening Table 3 for more information.

3. 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

4. Maximum power dissipation when output is shorted.

ꢀOTES: TRIPLE OUTPUT MODELS
1. ꢉ uaꢀanꢂeed bꢊ deꢃ ign, noꢂ ꢂeꢃ ꢂed.
2. 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 .
3. To maintain tight regulation over the full input voltage range a minimum load of 2% of full load should be used on all outputs.
4. To maintain the cross regulation specification, one of the auxiliaries must always provide a minimum of 20% of the total auxiliary power used.
ꢀegative Vout cross regulation is referenced to 50%/50% balanced loads (at 100% of total rated output power - full load).
5. Cross regulation is measured under the following conditions:
Condition 1: +POUT = 20 - 80%,/- POUT = 80 - 20%
Condition 2: - POUT = 20 - 80%, /+ POUT = 80 - 20%
6. 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.
7. Efficiency measured with all outputs at full load.
8. Maximum power dissipation when all outputs are shorted simultaneously.
9. Recovery time is measured from application of the transient to point at which VOUT is within 1% of VOUT at final value.
10. Transition time >10 µs.
11. Half load to/from full load.
12. Measured from release of inhibit or input voltage step.

Test methods are referenced to MIL-STD-883 as determined by MIL-PRF-38534.
ꢀotes:
1. Redmond site, Interpoint brand, has a DSCC approved Radiation Hardness
Assurance plan. Our SMD products with RHA “P”, “R” or “F” code met DSCC
requirements.
2. Space Prototypes are non-QML products and may not meet all of the require-
ments of MIL-PRF-38534. “O” in the RHA designator position in Interpoint model
numbers indicates DSCC RHA “-” defined as no RHA.
3. All processes are QML qualified and performed by certified operators.
4. ꢀot required by DSCC but performed to assure product quality.
5. Burn-in temperature designed to bring the case temperature to +125°C minimum.
6. High dose rate testing.
7. ꢀo upset at the pins.
