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.
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.
TID performance to 40 krad(si) characterized for ELDRS.
SEE performance to 85 MeV/mg/cm2. Transients are fully characterized for cross section and magnitude.
Worst case analysis, stress, radiation and reliability reports available.
