HYBRID - HIGH RELIABILITY
RADIATION HARDENED
DC-DC CONVERTER
ART28XXT SERIES
28V Input, Triple Output
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
systems. The extremely high level of radiation tolerance
inherent in the ART design is the culmination of
extensive research, thorough analysis and testing and
of careful component selection. Many of the proven
circuit design features characterizing the International
Rectifier standard product line were adapted for
incorporation into the ART topology. Capable of
uniformly high performance over long term exposures
in radiation intense environments, this series sets the
standard for distributed power systems demanding high
performance and reliability.
The ART converters are hermetically sealed in a
rugged, low profile package utilizing copper core pins
to minimize resistive DC losses. Long-term hermeticity
is assured through use of parallel seam welded lid
attachment along with International Rectifier’s rugged
ceramic pin-to-package seal. Axial orientation of the
leads facilitates preferred bulkhead mounting to the
principal heat-dissipating surface.
Manufactured in a facility fully qualified to MIL-PRF-38534,
these converters are fabricated utilizing DLA qualified
processes. For available screening options, refer to
device screening table in the data sheet.

Notes to SPECIFICATIONS
1. Operation outside absolute maximum/minimum limits may cause permanent damage to the device. Extended operation at the limits may permanently
degrade performance and affect reliability.
2. Device performance specified in Electrical Performance table is guaranteed when operated within recommended limits. Operation outside
recommended limits is not specified.
3. Parameter measured from 28V to 19 V or to 50V while loads remain fixed.
4. Parameter measured from nominal to minimum or maximum load conditions while line remains fixed.
5. Up to 750 mA is available from the dual outputs provided the total output power does not exceed 30W.
6. Guaranteed for a bandwidth of DC to 20MHz. Tested using a 20KHz to 2MHz bandwidth.
7. Load current is stepped for output under test while other outputs are fixed at half rated load.
8. Load current is fixed for output under test while other output loads are varied for any combination of minimum to maximum.
9. A capacitive load of any value from 0 to the specified maximum is permitted without comprise to DC performance. A capacitive load in excess of the
maximum limit may interfere with the proper operation of the converter’s short circuit protection, causing erratic behavior during turn on.
10. Parameter is tested as part of design characterization or after design or process changes. Thereafter, parameters shall be guaranteed to the limits
specified in the table.
11. Load transient rate of change, di/dt 2 A/µSec.
12. Recovery time is measured from the initiation of the transient to where VOUT has returned to within ±1% of its steady state value.
13. Line transient rate of change, dv/dt 50 V/µSec.
14. Turn on delay time is for either a step application of input power or a logical low to high transition on the enable pin (pin 3) while power is present at the
input.
