DESCRIPTION
the other and from the input. Sets are defined as follows:
Two paralleled power trains supplying a single output; one
independent power train providing a single output; and one
independent power train providing two outputs (neg. output is
cross-regulated). This product configuration eliminates cross
regulation effects between output sets.
The SMRT Series™ of DC/DC converters offers up to 35
watts of power in a radiation tolerant design. The low profile
SMRT converters are manufactured in Interpoint’s fully certified
and qualified MIL-STD-1772 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 include:
The SMRT 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 SMRT’s feed-forward compensation and
discontinuous topologies provide high levels (80 dB peak) of
input-to-output ripple rejection. A minimum load of 2% of full load
should be used on outputs at TID of 100k rads(Si) or greater to
ensure tight regulation over the full input range.
• Single Output: One two-phased single output
• Dual Output: Two single phase single outputs
• Triple Output: One single phase independent Main output and one
single phase dual output. (± Auxiliary output).
UNDERVOLTAGE LOCKOUT
The converters have an undervoltage lockout that will allow
power conversion at 17 volts on a rising input voltage and a
conversion shut-down on a falling voltage at approximately 14.5
volts.
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

28 VOLT INPUT – 35 WATT
INHIBIT FUNCTION
SCREENING
The SMRT Series incorporates an inhibit terminal that can be
used to disable internal switching. The converter is inhibited
when a low (≤ 0.4 V) signal is applied to the inhibit pin. In the
inhibit mode the inhibit pin current requirement is less than ~2
mA. The converter resumes normal operation when a high (≥ 2.4
V) signal or open circuit is applied to the inhibit pin. The open
SMRT 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
circuit voltage of the inhibit is 5 to 6 volts.The maximum allowable as “no RHA”. See “Class H and K, MIL-PRF-38534 Screening”
voltage applied to the inhibit pin is 10 VDC.
tables for more information.
EMI
The SMRT 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-CE102.
SYNCHRONIZATION
An isolated sync input allows this input to be connected to any of
the devices three returns. It can be referenced to the input return
or any of the output returns. Input current into this pin is limited
by a series 1k ohm resistance.
SENSE
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 sense line and the positive output.
OUTPUT VOLTAGE TRIM
The output voltage of each set can be trimmed up by up to 25%,
or down by up to 45% of nominal (varies by model, see trim
instructions). The following are “sets” of voltages in relation to
trim:
• Triple output models: Main output is one set, the dual outputs are
another set.
• Dual outputs: Each output is a “set.”
One set can be trimmed using the trim pin, the other set can be
trimmed (up only) using the sense pin.
• Single: One set

- DUAL UNITS OUTPUT A ONLY
(See trim tables on page 4)
RADIATION HARDENED
The SMRT 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

Notes
1. Guaranteed by design, not tested.
2. Maximum power dissipation when output is shorted.
3. Measured from release of inhibit or input voltage step.
4. Minimum value pre-load on all outputs of 2% of full load should be used on all outputs at TID of 100k rads(Si) and greater to ensure tight regulation
over full input voltage range.
5. Half load to/from full load; Transition time ≥ 10 μs.
6. Converter should not be inhibited or operated below 19 Vin above 5x10 rads (Si) total dose.
4
7. If 3.3S model is trimmed to the high end of its range, then minimum Vin = 22 V.
8. Converters meet MIL-STD-461 specification revisions for conducted emissions C-CE03 and D-/E-CE-102. The actual value of input ripple current
is much less, the limit in the characteristic table is based on measurement resolution.

Notes
1. Guaranteed by design, not tested.
2. The specified maximum current/power is available from each output.
3. Maximum power dissipation when both outputs are shorted simultaneously.
4. Measured from release of inhibit or input voltage step.
5. A minimum output load on all outputs of 2% of full load should be used on all outputs at TID of 100k rad(Si) or greater to ensure tight regulation over the full
input voltage range.
6. Half load to/from full load; Transition time ≥ 10 μs.
7. Converter should not be inhibited or operated below 19 Vin above 5x10 rads (Si) total dose.
4
8. If 3.3S model is trimmed to the high end of its range, then minimum Vin = 22 V.
9. Converters meet MIL-STD-461 specification revisions for conducted emissions C-CE03 and D-/E-CE-102. The actual value of input ripple current is much less, the limit in
the characteristic table is based on measurement resolution.

Test methods are referenced to MIL-STD-883 as determined by MIL-PRF-38534.
Notes:
1. Space Prototype (O), non-QML products, do not meet all of the requirements of MIL-PRF-38534.
2. Not applicable to EMI filters that have no wirebonds.
3. Not required by DSCC but performed to assure product quality.

Notes:
1. Our EMI filters are designed exclusively with passive components providing maximum tolerance for space environment requirements.
2. 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”.
3. Space Prototype (O), non-QML, products do not meet all of the requirements of MIL-PRF-38534.
4. Redmond site, Interpoint, has a Radiation Hardness assurance plan on file with DSCC. Our SMD products with RHA “P”, “R," "F" and "H"
code meet DSCC requirements.
