RADIATION HARDENED
DC-DC CONVERTER
Description
The LS-Series of DC-DC converters are, high reliability
devices designed for hostile radiation hardened
environments. The LS-Series provide up to 30 watts
output power, small size, low weight, integrated EMI
filtering and a high tolerance to environmental stresses
such as radiation, temperature extremes, mechanical
shock, and vibration. Extensive documentation
including, thermal analysis, stress analysis and reliability
predictions are available.
The LS-Series of converters incorporate a fixed
frequency single forward topology with magnetic
feedback and an internal EMI filter. These converters
are capable of meeting the conducted emissions
requirements of MIL-STD-461C without any additional
components. All models include an external inhibit port
and have an adjustable output voltage. They are
enclosed in a hermetic 1.5" x 2.3" x 0.425" steel package
and weigh less than 80 grams. The package utilizes
rugged ceramic feed-through copper core pins and is
sealed using parallel seam welding.
The LS-Series of DC-DC converters provide same
mechanical outline, power ratings, for backward pin
compatibility, to their lower radiation tolerant counterpart
M3L and Military series ATS DC-DC converters. The
common platform design allows for similarity between
military and space system architectures. For higher
output power applications the HM, M3H and M3G-Series
of DC-DC converters are recommended.
Manufactured in a facility fully qualified to MIL-PRF-
38534, these converters are fabricated utilizing DLA
Land and Maritime qualified processes. For available
screening options, refer to device screening table in the
data sheet.
Variations in electrical specifications and screening to
meet custom requirements can be accommodated.
