1.0 DESCRIPTION
1.2 SPACE LEVEL CHARACTERIZATIONS
The SVFA Series of space qualified point of load DC-DC
converters is specifically designed for the harsh radiation
environment of space applications. Performance is guaranteed
through the use of hardened semiconductor components,
radiation lot acceptance testing (RLAT) of non-hardened
components, and analysis. The SVFA Series has been
characterized for Total Ionizing Dose (TID) performance
including Enhanced Low Dose Rate Sensitivity (ELDRS) and for
Single Event Effects (SEE) according to VPT’s DLA-approved
Radiation Hardness Assurance (RHA) plan per MIL-PRF-38534,
Appendix G, Level P. Characterization is performed at both the
component level and at the SVFA Series hybrid converter level.
• Guaranteed TID performance to 40 krad(Si) including ELDRS
• SEE performance to 85 MeV-cm2/mg. Transients are fully
characterized for cross section and magnitude
• Worst-case analysis, stress, radiation, reliability reports available
1.3 MANUFACTURING AND COMPLIANCE
• Qualified to MIL-PRF-38534 Class H and Class K,
DLA SMD # 5962-16212
• MIL-PRF-38534 element evaluated components
• Manufactured in a MIL-PRF-38534 Class H and Class K facility
• MIL-STD-883
• ISO-9001
The SVFA Series of point of load DC-DC converters is radiation
tolerant and suited for use in low Earth orbit (LEO), medium
Earth orbit (MEO), geostationary orbit (GEO), deep space, and
launch vehicle programs.
