Terrestrial commercial applications may include nuclear power plants (near core) and research accelerators e.g. (Fermi Labs). This technology and products will also address emerging MDA radiation threats. These programs include MKV, AEKV, THAAD, AEGIS, and GMD for Blocks 2010, and beyond. With the new challenge of atmospheric neutrons to MDA High altitude airship (HAA) programs and NASA or Air Force UAV programs, this R&D will be timely solution. Other military applications may include strategic missiles (Trident and AF upgrades), as well as many DoD tactical weapon programs with nuclear survival levels. The applications for the technologies developed as part of this SBIR can literally be almost any platform that goes into space. Every rocket, satellite, experiment, etc. that goes into space has a need for memory storage capacity to some extent. By developing the technologies described in this SBIR, and then maturing these to flight-grade, the processing power available to spacecraft, satellite, and experiment designers will be increased significantly.
Virtually all NASA space programs have a demand for this proposed technology and product. NASA applications range from space shuttle, space station, earth sensing missions e.g. (EOS), and deep space missions. NASA programs/missions that will benefit include lunar landers and orbiters, Mars missions, solar system exploration e.g. (Titan, Juno, Gynemead, comet nucleus return, New Discovery and Living with a Star (LWS). New programs including both Ares, the Orion Crew Exploration Vehicle (CEV) and Commercial Orbiter Transportation Service (COTS) would benefit. Products evolving from this SBIR will be enabling for future programs such as Dawn, Aquarius, Kepler, Ocean Vector Winds, and space interferometry.","description":"The Space Micro Arizona State University (ASU) team will develop an all-digitally controlled, wide temperature range point-of-load switch-mode DC-DC regulator core with built-in self-test (BIST) functionality which meets space radiation requirements. In Phase I we will produce a design that can be fabricated into silicon in Phase II and demonstrate aspects of the design in the laboratory with some preexisting silicon circuits and discrete components.","startYear":2011,"startMonth":2,"endYear":2011,"endMonth":9,"statusDescription":"Completed","principalInvestigators":[{"contactId":3164090,"canUserEdit":false,"firstName":"David","lastName":"Strobel","fullName":"David Strobel","fullNameInverted":"Strobel, David","primaryEmail":"dstrobel@spacemicro.com","publicEmail":true,"nacontact":false},{"contactId":103290,"canUserEdit":false,"firstName":"Dave","lastName":"Strobel","fullName":"Dave J Strobel","fullNameInverted":"Strobel, Dave J","middleInitial":"J","primaryEmail":"dstrobel@spacemicro.com","publicEmail":true,"nacontact":false}],"programDirectors":[{"contactId":206378,"canUserEdit":false,"firstName":"Jason","lastName":"Kessler","fullName":"Jason L Kessler","fullNameInverted":"Kessler, Jason L","middleInitial":"L","primaryEmail":"jason.l.kessler@nasa.gov","publicEmail":true,"nacontact":false}],"programExecutives":[{"contactId":215154,"canUserEdit":false,"firstName":"Jennifer","lastName":"Gustetic","fullName":"Jennifer L Gustetic","fullNameInverted":"Gustetic, Jennifer L","middleInitial":"L","primaryEmail":"jennifer.l.gustetic@nasa.gov","publicEmail":true,"nacontact":false}],"programManagers":[{"contactId":62051,"canUserEdit":false,"firstName":"Carlos","lastName":"Torrez","fullName":"Carlos Torrez","fullNameInverted":"Torrez, Carlos","primaryEmail":"carlos.torrez@nasa.gov","publicEmail":true,"nacontact":false}],"projectManagers":[{"contactId":179160,"canUserEdit":false,"firstName":"Henry","lastName":"Fain","fullName":"Henry B Fain","fullNameInverted":"Fain, Henry B","middleInitial":"B","primaryEmail":"henry.b.fain@nasa.gov","publicEmail":true,"nacontact":false},{"contactId":461333,"canUserEdit":false,"firstName":"Theresa","lastName":"Stanley","fullName":"Theresa M Stanley","fullNameInverted":"Stanley, Theresa M","middleInitial":"M","primaryEmail":"theresa.m.stanley@nasa.gov","publicEmail":true,"nacontact":false}],"website":"","libraryItems":[{"file":{"fileExtension":"pdf","fileId":293586,"fileName":"SBIR_2010_1_BC_S3.05-8876","fileSize":335720,"objectId":290105,"objectType":{"lkuCodeId":889,"code":"LIBRARY_ITEMS","description":"Library Items","lkuCodeTypeId":182,"lkuCodeType":{"codeType":"OBJECT_TYPE","description":"Object Type"}},"objectTypeId":889,"fileSizeString":"327.9 KB"},"files":[{"fileExtension":"pdf","fileId":293586,"fileName":"SBIR_2010_1_BC_S3.05-8876","fileSize":335720,"objectId":290105,"objectType":{"lkuCodeId":889,"code":"LIBRARY_ITEMS","description":"Library Items","lkuCodeTypeId":182,"lkuCodeType":{"codeType":"OBJECT_TYPE","description":"Object Type"}},"objectTypeId":889,"fileSizeString":"327.9 KB"}],"id":290105,"title":"Briefing Chart","description":"All Digital Switch-Mode DC/DC Converters with BIST Functionality for Harsh Space Environments, Phase I","libraryItemTypeId":1222,"projectId":8593,"primary":false,"publishedDateString":"","contentType":{"lkuCodeId":1222,"code":"DOCUMENT","description":"Document","lkuCodeTypeId":341,"lkuCodeType":{"codeType":"LIBRARY_ITEM_TYPE","description":"Library Item Type"}}}],"transitions":[{"transitionId":64979,"projectId":8593,"transitionDate":"2011-09-01","path":"Closed Out","details":"All Digital Switch-Mode DC/DC Converters with BIST Functionality for Harsh Space Environments, Phase I Project Image","closeoutDocuments":[{"title":"Final Summary Chart Image","file":{"fileExtension":"pdf","fileId":305239,"fileName":"SBIR_10_1_S3.05-8876","fileSize":157166,"objectId":64979,"objectType":{"lkuCodeId":1841,"code":"TRANSITION_FILES","description":"Transition Files","lkuCodeTypeId":182,"lkuCodeType":{"codeType":"OBJECT_TYPE","description":"Object Type"}},"fileSizeString":"153.5 KB"},"transitionId":64979,"fileId":305239}],"infoText":"Closed out","infoTextExtra":"","dateText":"September 2011"}],"responsibleMd":{"acronym":"STMD","canUserEdit":false,"city":"","external":false,"linkCount":0,"organizationId":4875,"organizationName":"Space Technology Mission Directorate","organizationType":"NASA_Mission_Directorate","naorganization":false,"organizationTypePretty":"NASA Mission Directorate"},"program":{"acronym":"SBIR/STTR","active":true,"description":"
The NASA SBIR and STTR programs fund the research, development, and demonstration of innovative technologies that fulfill NASA needs as described in the annual Solicitations and have significant potential for successful commercialization. If you are a small business concern (SBC) with 500 or fewer employees or a non-profit RI such as a university or a research laboratory with ties to an SBC, then NASA encourages you to learn more about the SBIR and STTR programs as a potential source of seed funding for the development of your innovations.
The SBIR and STTR programs have 3 phases:
The SBIR and STTR Phase I contracts last for 6 months with a maximum funding of $125,000, and Phase II contracts last for 24 months with a maximum funding of $750,000 - $1.5 million.
Opportunity for Continued Technology Development Post-Phase II:
The NASA SBIR/STTR Program currently has in place two initiatives for supporting its small business partners past the basic Phase I and Phase II elements of the program that emphasize opportunities for commercialization. Specifically, the NASA SBIR/STTR Program has the Phase II Enhancement (Phase II-E) and Phase II eXpanded (Phase II-X) contract options.
