1.0 DESCRIPTION
1.2 SPACE LEVEL CHARACTERIZATIONS
The SVFL Series of space qualified 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 SVFL 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 SVFL Series hybrid converter level.
• Guaranteed TID performance to 30 krad(Si) including ELDRS
• SEE performance to 44 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 # 5962-11217
• MIL-PRF-38534 element evaluated components
• MIL-STD-461 C/D/E/F when used with appropriate VPT EMI filter
• Manufactured in a MIL-PRF-38534 Class H and Class K facility
• MIL-STD-883
• ISO-9001
The SVFL Series of 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.
