ART28XXT SERIES
28V Input,Three Output
ADVANCED ANALOG
HYBRID - HIGH RELIABILITY
RADIATION HARDENED DC/DC CONVERTER
Description
The ART Series of three output DC/DC converters are
designed specifically for use in the hostile radiation
environments characteristic of space and weapon sys-
tems. The extremely high level of radiation tolerance
inherent in the ART design is the culmination of exten-
sive research, thorough analysis and testing and of
careful component specification. Many of the best cir-
cuit design features characterizing the Advanced Ana-
log standard product line were adapted for incorpora-
ART
tion into the ART topology. Capable of uniformly high
performance over long term exposures in radiation in-
Features
n Total Dose > 100KRad (Si), 2:1margin
tense environments, this series sets the standard for
distributed power systems demanding high perfor-
mance and reliability.
n SEE hard to LET = 83 Mev.cm2 /mg
n Designed to MIL-PRF-38534 for Class K
n Derated per MIL-STD-975 & MIL-STD-1547
n Output Power Range 3 to 30 Watts
n 19 to 50 Volt Input Range
The ART converters are hermetically sealed in a rug-
ged, low profile package utilizing copper core pins to
minimize resistive DC losses. Long-term hermeticity is
assured through use of parallel seam welded lid at-
tachment along with Advanced Analog’s rugged ce-
ramic pin-to-package seal. Axial orentation of the leads
facilitates preferred bulkhead mounting to the principal
heat-dissipating surface.
n Input Undervoltage Lockout
n High Electrical Efficiency > 80%
n Full Performance from -55°C to +125°C
n Continuous Short Circuit Protection
n 12.8 W / in3 Output Power Density
n True Hermetic Package
n External Inhibit Port
n Externally Synchronizable
n Fault Tolerant Design
Manufactured in a facility fully qualified to MIL-PRF-
38534, these converters are fabricated utilizing DSSC
qualified processes, and are fully compliant to Class H
while being fully processed to the requirements of Class
K. Complete PI & CI testing has been completed in-
cluding Group C life test. Variations in electrical, me-
chanical and screening specifications can be accom-
modated. Contact Advanced Analog for special require-
ments.
n 5V, ±12 or ±15 Volts Outputs Available
