S2800_15 Datasheet, PDF (1/9 Pages) International Rectifier – 28V Input, Single/Dual Output

PD-94584K
HYBRID-HIGH RELIABILITY
RADIATION HARDENED
LOW POWER
DC-DC CONVERTER
S-SERIES
28V Input, Single/Dual Output
Description
The S-Series of DC-DC converters are low power
radiation hardened, high reliability devices designed
for hostile radiation environments such as those
encountered by geostationary earth orbit satellites, deep
space probes and communication systems. Features
include small size, high efficiency, low weight and a
high tolerance to total ionizing dose, single event effects,
and environmental stresses such as temperature
extremes, mechanical shock, and vibration. Extensive
documentation including Radiation Susceptibility,
Thermal Analysis, Stress Analysis and MTBF are
available.
The converters incorporate a fixed frequency single
ended forward topology with magnetic feedback and
an internal EMI filter utilizing large multilayer ceramic
capacitors processed per MIL-PRF-49470 for improved
reliability. All models include an external inhibit port .
They are encased in a hermetic 1.71” x 1.31” x 0.45”
steel package and weigh less than 50 grams. The
package utilizes rugged ceramic feed-through copper
core pins and is hermetically 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 S-Series converters are
available for system development purposes. Variations
inelectrical specifications and screening to meet custom
requirements can be accommodated.
