DeSign FeatureS
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 VDC nominal input. On dual output
models, up to 70% of the rated output power can be drawn from
either the positive or negative outputs. Current sharing allows
the units to be paralleled for total power of up to 285 watts. The
welded, hermetically sealed package is only 3.005 x 1.505 x
0.400 inches.
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.
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) Radiation
Hardness Assurance 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.
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. The output voltage on single SMFLHP
models can be easily trimmed up by adding an external resistor.
See “Figure 2: Sense Connections and Trim Table – Single
Output Models” on page 3 for voltage changes with different
resistor values.

converter is designated as a master. The SLAVE pin (pin 11) of
inhibit
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. 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 1 shows the typical setup for two or three units in parallel.
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. An active low (<0.8
volts) is required between INH1 (pin 4) and Input Common (pin
2) to inhibit the converter. An active low (<0.5 volts) is required
between INH2 (pin 12) and Output Common (pin 8) to inhibit the
converter. The application of intermediate voltages to these pins
(1.5 to 10.5 volts) should be avoided.
Note that synchronizing the units together (though shown in the
figure) is not required for current sharing 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 pin (pin 9).
current Sharing anD parallel OperatiOn
Multiple SMFLHP converters may be used in parallel to drive
a common load. See “Figure 1: Parallel Connections – Single
Output Models” on page 2. 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
When paralleled, up to 95% of the total combined power ratings
of the SMFLHP converters is available at the load. Overload
and short circuit performance are not adversely affected during
parallel operation.

Notes
1. No one converter may carry more than its maximum rated current.
2. Although 95% of the maximum current of paralleled converters is available, individual converter operation, load and layout
may affect the actual current shared. Contact Applications Engineering for more information at powerapps@crane-eg.com.

Test methods are referenced to MIL-STD-883 as determined by MIL-PRF-38534.
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.
