VPT, Inc., a HEICO company announces the availability of its SVLFL5000 Series of space-qualified DC-DC converters. Characterized by Total Ionizing Dose (TID) performance, including Enhanced Low Dose Rate Sensitivity (ELDRS), to 60 krad, the 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.

The SVLFL5000 Series (120W) has a wide input voltage range of 30 to 60 V and comes in single (SVLFL5000S) and dual (SVLFL5000D) outputs. The series will be qualified to MIL-PRF-38534 Class H and Class K pending DLA approval and is designed specifically for space applications facing harsh radiation environments, with guaranteed performance using hardened semiconductor components, radiation lot acceptance testing (RLAT) of non-hardened components, and analysis.

“VPT is excited to add the SVLFL5000S/D converters to the SVL families.” Vice President of Engineering, Leonard Leslie stated.  “These converters are designed to operate up to 100 W, and offer additional functionality such as switching frequency synchronization input and output and a current share feature allowing multiple converters to be operated in parallel to scale to higher power applications.”

VPT’s Vice President, International Sales and Marketing, Malcolm Campbell, added, “With the SVLFL50 family’s release, VPT is proud to offer a full line of 50 V input DC-DC converters designed specifically for high reliability space applications. Our 50 V input product line now ranges from 6W to 100+W of output power in single and dual output models. We also offer a full line of compatible EMI input filters.”
