Description
The D-Series of DC-DC converters are low power
radiation hardened, high reliability devices designed
for 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. All
components are fully derated to meet the requirements
of EEE-INST-002. Extensive documentation including
worst case analysis, radiation susceptibility, thermal
analysis, stress analysis, and reliability analysis are
available.
.
The D-Series converters have two outputs, each is
independently regulated. The outputs can be both
positive or one positive and one negative. The D-Series
converters incorporate a fixed frequency flyback power
stage topology and internal EMI filter. The converters
include an enhanced input EMI filter that meets most
major satellite power buses. The converters can be
remotely turned on and off via an Inhibit pin. Additional
Inhibit pins are also provided to control the outputs
individually. This feature facilitates turn-on outputs
sequencing if desired. Each converter is encased in a
cold rolled steel hermetic package. The package
measures 1.80"L x 1.40"W x 0.42"H and weighs less
than 55 grams.The package utilizes rugged ceramic
feed-through copper core pins and is hermetically sealed
using parallel seam welding. Two package options are
available. Please refer to page 8 for I/O configurations.
Environmental screening includes temperature cycling,
constant acceleration, fine and gross leak, and burn-in
as specified by MIL-PRF-38534 for class H hybrids.
