Abstract :
This paper describes the simulations, ionizing dose, neutron and SEE exposures for the radiation hard "ground-up" design, triple output DC/DC converter in both 10 Watt and 30 Watt configurations plus a triple output series regulator. Specifically, the testing performed was to confirm operation in Earth geosynchronous space environments. Post-ionizing dose, post 1019.4 annealing data, post neutron and post SEE data are presented. The radiation evaluations on ART2815T samples demonstrated performance within specification to 1.5E6 Rads (Si), 1E13 n/cm2, no SEU or SEL to LET of 83 and post 1019.4 anneal yielding all parameters within 1% of pre-irradiation values.
