28V Input, Single Output
Description
The Z-Series of DC/DC converter modules has been
specifically designed in response to the need for low
voltage at moderate current levels supplied with the
high efficiency and tight regulation dictated by modern
digital processing applications. These converters are
designed specifically for operation in radiation environ-
ments that are presented to commercial communica-
tion satellites operating in long term GEO and LEO or-
bits. They have been created to complement the spec-
trum of electrical and radiation performance available
in the Advanced Analog ART2815T and M3G-Series
converters. Requirements occurring in space vehicles
operating in Geostationary orbits, launch boosters, sci-
entific space probes and similar applications requiring
a low voltage, high efficiency converter with well char-
acterized radiation hardness performance will be opti-
mally satisfied by the Z-Series converters.
An additional benefit of the Z-Series is high power den-
sity. This is facilitated by utilizing the best features of
chip and wire hybrid technology and surface mount fab-
rication techniques. The hybrid portion is fabricated in
a facility fully qualified to MIL-PRF-38534 and pro-
cessed to class K requirements. The standard process-
ing adopted for the Z-Series module has been created
to assure with margin the reliability required for space
applications. Applicable generic lot qualification test
data including radiation performance will be made avail-
able on request. Variations to the standard screening
may be accommodated. Consult IR Santa Clara for
special requirements.
