SVL Series: Space Qualified DC-DC Converters
SVL Series: Space Qualified DC-DC Converters

VPT, Inc. has announced the availability of its SVL series of 28 volts, space-qualified DC-DC converters with a wide input voltage range of 15V to 50V, designed specifically for space applications facing harsh radiation environments. This series is operable over the full military temperature range (-55 °C to +125 °C) with no power derating and is suited for use in low Earth orbit (LEO), medium Earth orbit (MEO), geostationary orbit (GEO), deep space missions, and launch vehicle programs. This Series is characterized by Total Ionizing Dose (TID) performance and includes Enhanced Low Dose Rate Sensitivity (ELDRS).


SVLFL, SVLHF, SVLTR, and SVLSA Series come with guaranteed performance through the use of hardened semiconductor components, radiation lot acceptance testing (RLAT) of non-hardened components, and analysis. The SVLFL and SVLTR are qualified to MIL-PRF-38534 Class H and Class K, and Radiation Hardness Assurance (RHA) Level R, while the SVLHF and SVLSA have been submitted for qualification.
