M3G-SERIES
50V Input, Triple Output
Description
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.
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.
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 M3G-Series converters are available
for system development purposes. Variations in electrical
specifications and screening to meet custom requirements can
be accommodated.
