description
similar to primary current mode control and allows for ease of
paralleling, but without the cost and complexity.
The 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 paral-
leled for total power of up to 148 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).
Sc r e e n i n g
in h i b i t
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 - 3 for more information.
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). The appli-
cation of intermediate voltages to these pins (1.5 to 10.5 volts)
should be avoided.
De S i g n Fe a t u r e S
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.
Sy n c
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 (see Application Note
titled “Inhibit and Synchronization”).
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
mode feedback loop improves transient response in a manner
cu r r e n t a n D Pa r a l l e l OP e r a t i O n
Multiple single output SMFL converters may be used in parallel
to drive a common load. In this mode of operation the load
current is shared by two or three SMFL converters. In current

Notes:
1. Redmond site, Interpoint, has a DSCC approved Radiation Hardness Assurance plan. Our SMD products with RHA “P” or “R” 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. No upset at the pins.
