DESCRIPTION
The SMTR Series™ of 28 volt DC/DC converters offers up to
30 watts of output power from single or dual output configurations.
The operate over the full military temperature range of –55°C to
+125°C with up to 84% efficiency. SMTR converters are packaged
in hermetically sealed metal enclosures, making them ideal for use
in military, aerospace and other high reliability applications.
SCREENING AND REPORTS
SMTR converters offer three screening options (Standard, Class H,
or Class K) and two levels of radiation hardness (O or R). See
Tables 1, 2, and 3 for more information. Detailed reports on product
performance are also available and are listed in Table 4.
CONVERTER DESIGN
The SMTR converters are constant frequency, pulse-width modulated switching regulators which use a quasi-square wave, single
ended, forward converter design. Tight load regulation is maintained
by using a wide bandwidth magnetic feedback and, on single output
models, through use of remote sense. On dual output models, the
positive output is independently regulated and the negative output is
cross regulated through the use of tightly coupled magnetics.
Indefinite short circuit protection and overload protection are
provided by a constant current-limit feature. This protective system
senses current in the converter’s secondary stage and limits it to
approximately 115% of the maximum rated output current.
SMTR converters are provided with internal filtering capacitors that
help reduce the need for external components in normal operation.
For systems that require compliance with MIL-STD-461C’s CE03
standard, Interpoint offers filter/transient suppression modules
(including the FMC-461, FMD-461 and FM-704A series filters) which
will result in compliance. For the lowest noise performance, connection of the case to input common is recommended. The connection
can be hard-wired or AC coupled with a small ceramic bypass
capacitor.
®
SYNCHRONIZATION
Synchronizing the converter with the system clock allows the
designer to confine switching noise to clock transitions, minimizing
interference and reducing the need for filtering. In sync mode, the
converter will run at any frequency between 500 kHz and 675 kHz.
The sync control operates with a quasi-TTL signal at any duty cycle
between 40% and 60%. The sync pin should be connected to input
common pin when not in use.
WIDE VOLTAGE RANGE
SMTR converters are designed to provide full power operation over
a full 16 to 40 Vdc voltage range. Operation below 16 volts,
including MIL-STD-704D emergency power conditions is possible
with derated power.
IMPROVED DYNAMIC RESPONSE
The SMTR Series feed-forward compensation system provides
excellent dynamic response and noise rejection. Audio rejection is
typically 50 dB. The min. to max. step line transient response is typically less than 4%.
INHIBIT FUNCTION
SMTR converters provide an inhibit terminal that can be used to
disable internal switching, resulting in no output and very low
quiescent input current. The converter is inhibited when a TTL
compatible low (≤0.8V) is applied to the inhibit pin. The unit is
enabled when the pin, which is internally connected to a pull-up
resistor, is left unconnected or is connected to an open-collector
gate. The open circuit output voltage associated with the inhibit pin
is 9 to 11 Vdc. In the inhibit mode, a maximum of 8 mA must be sunk
from the inhibit pin.

Notes for Remote Sense and Trim
1. When trimming output voltage and/or remote sensing, the total output
voltage increase must be less than 0.6 volts at the converters pins to
maintain specified performance.
2. If neither voltage trim nor remote sense will be used, connect pin 3 to
pin 4 and pin 5 to pin 6 or the output voltage will increase by 1.2 volts.
3. CAUTION: The converter will be permanently damaged if the positive
remote sense (pin 6) is shorted to ground. Damage may also result if
the output common or positive output is disconnected from the load with
the remote sense leads connected to the load.
