DESCRIPTION
The SMRT Series™ of DC/DC converters offers up to 35
watts of power in a radiation tolerant design. The low profile
SMRT converters are manufactured in Interpoint’s fully certified
and qualified MIL-STD-1772 production facility and packaged
in hermetically sealed steel cases. They are ideal for use in
programs requiring high reliability, small size, and high levels of
radiation hardening assurance.
The SMRT converters are switching regulators which use a two-
phase, phase shifted flyback design with a nominal switching
frequency of 300 kHz. Close regulation is maintained with
advanced constant frequency pulse width modulation design
techniques. The SMRT’s feed-forward compensation and
discontinuous topologies provide high levels (80 dB peak) of
input-to-output ripple rejection. A minimum load of 2% of full load
should be used on outputs at TID of 100k rads(Si) or greater to
ensure tight regulation over the full input range.
Two independent feedback loops are used to regulate the dual
and triple outputs, one feedback loop regulates the two-phased
single output. Each set of outputs is electrically isolated from
the other and from the input. Sets are defined as follows:
Two paralleled power trains supplying a single output; one
independent power train providing a single output; and one
independent power train providing two outputs (neg. output is
cross-regulated). This product configuration eliminates cross
regulation effects between output sets.
Configurations include:
• Single Output: One two-phased single output
• Dual Output: Two single phase single outputs
• Triple Output: One single phase independent Main output and one
single phase dual output. (± Auxiliary output).

The converters have an undervoltage lockout that will allow
power conversion at 17 volts on a rising input voltage and a
conversion shut-down on a falling voltage at approximately 14.5
volts.
