HYBRID-HIGH RELIABILITY
RADIATION HARDENED
DC-DC CONVERTER
PD-97812
LSO SERIES
28V Input, Single/Dual Output
Description
The LSO Series of DC-DC converters are, high reliability
devices designed for hostile radiation hardened
environments. The design is based on the heritage-rich
LS Series with enhanced functional performance and
an inclusion of an output overvoltage protection. The
LSO 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-1547, MIL-STD-975 and NASA EEE-INST-
002. Extensive documentation including, thermal
analysis, stress analysis and reliability predictions are
available.
The LSO 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. The converters
are overload, short circuit and output over-voltage
protected. They are enclosed in a hermetic 3.5" x 2.5" x
0.475" H steel package and weigh less than 125 grams.
The package utilizes rugged ceramic feed-through
copper core pins and is sealed using parallel seam
welding.
Manufactured in a facility fully qualified to MIL-PRF-
38534, these converters are fabricated utilizing DLA
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.
