description
The Interpoint® SMFLHP Series™ 28 volt dc-dc converters are
rated up to 100 watts output power over a -55°C to +125°C
­temperature range with a 28 V nominal input. On dual output
models, up to 70% of the rated output power can be drawn from
either the positive or negative outputs. The welded, hermetically
sealed package is only 3.005 x 1.505 x 0.400 inches.
Screening
SMFLHP 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-PRF-38534. Interpoint model numbers use an “O” in the
RHA designator position to indicate the “-” (dash) RHA level of
MIL-PRF-38534, which is defined as “no RHA”. See “Table 9:
Element Evaluation” on page 14 and “Table 10: Environmental
Screening and RHA Levels” on page 15 for more information.
Design Features
The SMFLHP Series converters are switching regulators that use
a quasi-square wave, single ended forward converter design with
a constant switching frequency of 600 kHz.

Isolation between input and output circuits is provided with a
transformer in the forward path and wide bandwidth magnetic
coupling in the feedback control loop. The SMFLHP Series
uses a unique dual loop feedback technique that controls output
current with an inner feedback loop and output voltage with a
cascaded voltage mode feedback loop.
The additional secondary current mode feedback loop improves
transient response in a manner similar to primary current mode
control and allows for ease of paralleling.
Tight load regulation is achieved through a wide-bandwidth
magnetic feedback circuit.
Inhibit
The SMFLHP Series converters have two inhibit terminals
(INH1 and INH2) that can be used to disable power conversion,
resulting in a very low quiescent input current. See Table 5 on
page 6 for specifications.
Sync
Converters may be synced to an external clock (525 to 675 kHz)
or to one another by using the sync in or out pins. See Table 5 on
page 6 for specifications.

28 Volt input – 100 Watt
Sense and Trim
The units designated as slaves have the MSTR/INH2 pin (pin 12)
connected to the SNS RTN pin (pin 9) of the master unit. Figure 2
on page 3 shows the typical setup for two or three units in
parallel.
Current Sharing and Parallel Operation
A second slave unit may be placed in parallel with a master and
slave; this requires the TRI pin (pin 3) of the master unit to be
connected to the SNS RTN pins (pin 9) Figure 2.
Single output models provide sense to maintain voltage at the
load. The converters output voltage can also be trimmed up. See
Figure 1.
Multiple SMFLHP converters may be used in parallel to drive a
common load. Only single output models with SENSE and SNS
RTN can be used in the share mode. In this mode of operation
the load current is shared by two or three SMFLHP converters.
In current sharing mode, one SMFLHP converter is designated
as a master. The SLAVE pin (pin 11) of the master is left
unconnected and the MSTR/INH2 pin (pin 12) of the master is
connected to the SLAVE pin (pin 11) of the slave units.

In current sharing mode, the converters function as a current
source. For this reason it is important that their outputs be
connected to the common ground at all times to prevent an

Notes
1. No one converter may carry more than its maximum rated current.
2. Individual converter operation, load and layout may affect the actual current shared. Contact Applications Engineering for more
information at [email protected].
3. When paralleling SMFLs a diode is required at the input of each inhibit pin as SMFLs do not have an internal diode on the
inhibit pin.

2. Number of Outputs: S is a single output and D is a dual output.
3. Case Options: For the standard case (“Figure 18: Case U” on page 12) leave the case option blank. For the down-leaded case option
(“Figure 19: Case V” on page 13,) insert the letter V in the case option position.
4. Screening: A screening level of O is a Space Prototype and is only used with RHA O. See “Table 9: Element Evaluation” on page 14 and
“Table 10: Environmental Screening and RHA Levels” on page 15 for more information.
5. 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 “Table 10: Environmental Screening
and RHA Levels” on page 15 for more information.

2. Dual outputs: The over-current limit will trigger when the sum of the currents from
both outputs reaches 125% (typical value) of the maximum rated “total” current of

Notes
1. Guaranteed by qualification test and/or analysis. Not an in-line test.
2.Up to 70% of the total output power/current is available from either output
provided the opposite output is carrying 30% of the power/current in use.
3. Effect on negative Vout from 50%/50% loads to 30%/70% or 70%/30% loads.
4. Effect on negative Vout from 50%/50% loads to 10% then 50% load on

mA p-p
5.Converter will shut down above approximately 45V but will be undamaged and
will restart when voltage drops into normal range.
6.Recovery time is measured from application of the transient to point at which
Vout is within 1% of final value.
7. Tested on release from inhibit.
8. Shall not compromise dc performance.
9. Applies to each output.

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.
