DESCRIPTION
The Intepoint™ SMTR Series™ of 28 volt DC/DC converters
offers up to 30 watts of output power from single, dual or
triple output configurations. They operate over the full military
temperature range of -55°C to +125°C with up to 84% efficiency
(up to 73% efficiency triple models). SMTR converters are
packaged in hermetically sealed metal enclosures, making them
ideal for use in military, aerospace and other high reliability
applications.

SMTR 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-STD-
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 for more information.
SMTR converters have an internal input filter that help reduce
the need for external components in normal operation. Use our
SFMC EMI input filter to meet the requirements of MIL-STD-
461C’s CE03. 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. 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 125% of the maximum rated
output current.

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. The SMTR Triple Series DC/DC converter’s
design includes individual regulators on the auxiliary outputs
which provide for no cross regulation error when a minimum
300 mA load is maintained on the main (+5 V) output.
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 an active high
at any duty cycle between 40% and 60%. The sync pin should be
connected to input common pin when not in use.

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.

The SMTR Series feed-forward compensation system provides
excellent dynamic response and noise rejection. Audio rejection
is typically 40 dB (50 dB for Triple output models). The min. to
max. step line transient response is typically less than 4%.
