HYBRID-HIGH RELIABILITY
RADIATION TOLERANT
DC-DC CONVERTER
PD-94519C
M3L-SERIES
+28V Input, Single/Dual Output
Description
The M3L-Series of DC-DC converters are radiation tolerant,
high reliability devices designed for moderate radiation
environments such as those encountered by low earth orbit
satellites and launch vehicles. For higher radiation environments,
the M3G-Series of DC-DC converters is recommended.
Features include small size, low weight and a high tolerance to
total ionizing dose, single event effects and environmental
stresses such as temperature extremes, mechanical shock,
and vibration. All components are fully de-rated to meet the
requirements of MIL-STD-975 and MIL-STD-1547 and
GSFC PPL-21 Appendix B. Extensive documentation including
Radiation Susceptibility, Thermal Analysis, Stress Analysis
and MTBF are available.
The 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 and conducted susceptibility 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 85 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 Land and
Maritime qualified processes. For available screening
options, refer to device screening table in the data sheet.
Non-flight versions of the M3L-Series converters are
available for system development purposes. Variations in
electrical specifications and screening to meet custom
requirements can be accommodated. Consult IR HiRel
San Jose for special requirements.
