A minimum load of 2% of full load should be used on outputs at
TID of 100 kRad(Si) or greater to ensure tight regulation over the
full input range. The converter should not be inhibited or oper-
ated below 19 Vin above 5x104 rad(Si) total dose.
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 certi-
fied and qualified MIL-PRF-38534 production facility and pack-
aged in hermetically sealed steel cases. They are ideal for use in
programs requiring high reliability, small size, and high levels of
radiation hardening assurance.
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 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
converterꢀasꢀtheꢀSMRT28ꢀInhibitꢀpinꢀcanꢀsinkꢀcurrent.ꢀWhenꢀ
pulling multiple inhibit signals low a separate interface is recom-
mended 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 resumes
normalꢀoperationꢀwhenꢀaꢀhighꢀ(≥ꢀ2.4ꢀV)ꢀsignalꢀorꢀopenꢀcircuitꢀisꢀ
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
125% of nominal (varies by model, see trim instructions on page
4). The following are “sets” of voltages in relation to trim:

12V Vmax = 14.68 V

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 contin-
uous normal operation through radiation levels associated with
space missions and in tactical and strategic military environ-
ments. The converters will operate normally in radiation environ-
ments 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 radia-
tion environments is required.

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.
5. Recovery time is measured from application of the transient to point at which VOUT is within 1% of VOUT at final value.

Electrical Characteristics: -55°C to +125°C Tc, 28 VDC Vin, 100% load, unless otherwise specified.
ꢀOTES: TRIPLE OUTPUT MODELS
1. ꢊꢀꢄꢃꢄnꢁꢂꢂd by dꢂꢈign, noꢁ ꢁꢂꢈꢁꢂd.
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.

ꢀotes:
1. Redmond site, Interpoint, has a DSCC approved Radiation Hardness Assurance plan. Our SMD products with RHA “P”, “R,” or “F” code
meet DSCC requirements.
2. Space Prototype (O), non-QML, products do not meet all of the requirements of MIL-PRF-38534.
3. 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”
4. ꢀo upset at the pins.
