description
mode feedback loop improves transient response in a manner
similar to primary current mode control and allows for ease of
paralleling, but without the cost and complexity.
The Interpoint™ SMFL Series™ 28-volt DC/DC converters
are rated up to 65 watts output power over a -55° 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 185 watts. The
welded, hermetically sealed package is only 3.0 x 1.5 x 0.40
inches, giving the series an overall power density of up to 43
watts per cubic inch.
The constant frequency, pulse-width modulated converters use
a quasi-square wave single-ended forward design. Tight load
regulation is achieved through a wide-bandwidth magnetic feed-
back circuit. The output voltage on single SMFL models can
be trimmed to a specific output voltage by adding an external
resistor (see Figure 1 for resistor values).
Screening
inhibit
SMFL converters, also available on SMD drawings, offer the
following screening options: 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 Screening
Tables 1 and 2
The SMFL 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 and no generation
of switching noise. An active low (<0.8 volts) is required to inhibit
the converter between INH1 (pin 4) and Input Common (pin
2). An active low (<0.5 volts) is required to inhibit the converter
between INH2 (pin 12) and Output Common (pin 8).
Sync
DeSign FeatureS
SMFL Series converters are switching regulators that use a
quasi-square wave, single ended forward converter design with a
constant switching frequency of 600 kHz typical.
Converters may be synced to an external clock (525 to 675 kHz)
or to one another by using the sync in or out pins. The nominal
free-run switching frequency is 600 kHz.
Isolation between input and output circuits is provided with a
transformer in the forward path and a wide bandwidth magnetic
coupling in the feedback control loop. The SMFL uses a unique
dual loop feedback technique that controls output current with
an inner feedback loop and an output voltage with a cascaded
voltage mode feedback loop. The additional secondary current
current Share anD Parallel OPeratiOn
Multiple SMFL converters may be used in parallel to drive a
common load (see Figure 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

1. No one converter may carry more than its maximum rated current.

affect the actual current shared. Contact Applications Engineering for more information 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.
