VPT’s SVLTR5000S and SVLTR5000D space-qualified DC-DC converters are now DLA qualified, released on SMD# 5962-22211 and 5962-22212, respectively.
The SVLTR Series 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 SVLTR 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 L. Characterization is performed at both the component level and at the SVLTR Series hybrid converter level. Radiation-hardened to TID levels of 60 krad(Si) and SEE to 85 MeV/mg/cm2, the SVLTR Series of DC-DC Converters is suited for use in many low Earth orbit (LEO), medium Earth orbit (MEO), geostationary orbit (GEO), deep space, and launch vehicle programs.
