Features
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.
Applications
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. All components are fully de-rated
to meet the requirements of MIL-STD-975. 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.
Variations in electrical specifications and screening to
meet custom requirements can be accommodated.
n Geo Synchronous Satellite
n Low Earth Orbit
n Deep Space Probe
n Communication and Display Systems
n Payload and Experiment LVPS

28V Input, Single/Dual Output
HYBRID - HIGH RELIABILITY
RADIATION HARDENED
DC-DC CONVERTER
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.
