Surge Stoppers Ease MIL-STD-1275D Compliance
Design Note 534
Dan Eddleman
Introduction
A military vehicle is a tough environment for electronics, where the potential for damaging power supply
fluctuations is high. U.S. Department of Defense MILSTD-1275D sets down the requirements for electronics when powered from a 28V supply, ensuring that
electronics survive in the field.
MIL-STD-1275D compliance can be achieved by brute
force, shunting high energy levels to ground using bulky
passive components. This method does not guarantee
power delivery to downstream electronics and can require replacing damaged protection components when
they do their job. A more compelling solution is to use
high voltage surge stoppers such as the LTC В®4366 and
LTВ®4363, which use series MOSFETs to limit the output
voltage when faced with input voltage spikes and surges.
A surge stopper reference design for MIL-STD-1275D
is available as Linear Technology demonstration circuit
DC2150A-C. This board limits its output voltage to 44V
when faced with input voltages as high as 250V, while
providing 4A of current to the output in all circumstances
except the В±7V ripple test, when the available current
is reduced to 2.8A. In most circumstances, satisfying
MIL-STD-1275D is as simple as placing this circuit in …

Compliance by Replacing Bulky Passive Components
Dan Eddleman Electronics in a military vehicle face a unique set of
challenges, chief among them operation from a perverse
power supply. Recognizing the difficult power supply
fluctuations that occur in the field, the US Department
of Defense created MIL-STD-1275D to set down the
requirements of electrical systems powered from a
military vehicleвЂ™s 28V supply. Designing systems to
withstand MIL-STD-1275DвЂ™s surge and related transients
traditionally requires large and expensive passive
components. Linear TechnologyвЂ™s surge stopper product
line is well suited to protecting systems from this type
of surge while reducing the cost and solution size.
MIL-STD-1275D REQUIREMENTS MIL-STD-1275D defines a variety of
conditions, most importantly those
of steady state operation, starting disturbances, spikes, surges, and ripple.
MIL-STD-1275D lays down requirements for each of these conditions
in three separate вЂњmodes of operationвЂќ: starting mode, normal operating mode, and generator-only mode.
Before describing the specifics of spikes,
surges, ripple, and other requirements, letвЂ™s
first look at the modes of operation. Not
surprisingly, вЂњstarting modeвЂќ describes …
