Non-flight versions of the M3G-Series converters are
available for system development purposes. Variations
in electrical specifications and screening to meet custom
requirements can be accommodated.
The M3G-Series of DC/DC converters are radiation
hardened, high reliability converters designed for
extended operation in hostile environments. Their small
size and low weight make them ideal for applications
such as geostationary earth orbit satellites and deep
space probes. They exhibit 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 derated
to meet the requirements of MIL-STD-975, MIL-STD-
1547 and GSFC PPL-21 Appendix B.
The converters incorporate a fixed frequency single
ended forward topology with magnetic feedback and
an internal EMI filter that utilizes multilayer ceramic
capacitors that are subjected to extensive lot screening
for optimum reliability. These converters are capable
of meeting the conducted emissions and conducted
susceptibility requirements of MIL-STD-461C without
any additional components. External inhibit and
synchronization input and output allow these converters
to be easily incorporated into larger power systems.
They are enclosed in a hermetic 3" x 2" x 0.475" package
constructed of an Aluminum-Silicon-Carbide (AlSiC)
base and an Alloy 48 ring frame and they weigh less
than 110 grams. The package utilizes rugged ceramic
feed-through copper core pins and is sealed using
parallel seam welding.
n Deep Space Satellites / Probes
n Strategic Weapons and Communication System
M3G
Manufactured in a facility fully qualified to MIL-PRF-
38534, these converters are fabricated utilizing DSCC
qualified processes. For available screening options,
refer to device screening table in the data sheet.
