HIGH RELIABILITY RADIATION
HARDENED DC-DC CONVERTER
M3G2803R305R4T
28V 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 feed back and
an internal EMI filter that utilizes metallized film capacitors
instead of large multilayer ceramic capacitors for
improved 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 3.5" x 2.5" x 0.475"
package constructed of an Aluminum/Silicon-Carbide
(Al/SiC) 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.
Full environmental screening includes temperature
cycling, constant acceleration, fine and gross leak,
particle impact noise detection (PIND), radiographic and
320 hours burn-in.
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.
