ARM28XXT Series
Radiation Performance
The radiation tolerance characteristics inherent in the
ARM28XXT converter are based on the results of the
ground-up design effort on the ART2800T program and
started with specific radiation design goals. By imposing
sufficiently large margins on those electrical parameters
subject to the degrading effects of radiation, appropriate
elements were selected for incorporation into the
ART2800T circuit. Known radiation data was utilized for
input to PSPICE and RadSPICE in the generation of circuit
performance verification analyses. Thus, electrical
performance capability under all environmental conditions
including radiation was well understood before first
application of power to the inputs.
radiation performance variations. Radiation tests on
random ART2800T manufacturing lots provide continued
confirmation of the soundness of the design goals as well
as justification for the element selection criteria.
To achieve the radiation levels specified for the ARM28XXT,
the ART2800T topology is utilized as the basis but lot
assurance testing is utilized as part of the screening
process to assure the specified level. Each ARM28XXT
converter is delivered with lot test data at the hybrid level
supporting the minimum TID specification. Other radiation
specifications are assured by design and generic data are
available on request.
The principal ART2800T design goal was a converter
topology, which because of large design margins, had
radiation performance essentially independent of wafer-lot
