SVRTR2800S DC-DC Converter

VPT’s SVR Series of DC-DC converters deliver a qualified power solution for your next LEO, MEO, GEO, deep space, and launch programs. Rad hard, qualified to MIL-PRF-38534 Class K on DLA SMDs, and designed for TOR compliance, these modules help you get your system off the ground fast. View VPT’s space program heritage.

Combine our extensive family of DC-DC converters for space with VPT’s point of load converters for space and EMI filters for space to create a light weight, extremely efficient, space-qualified distributed power system.

Delivering 40W from a small hermetic package, the SVRTR Series DC-DC converter is guaranteed radiation hardened including ELDRS plus it’s designed for Aerospace TOR compliance for the longevity of your space mission.

Features:

  • Single outputs of 3.3, 5, 12, and 15 V
  • Up to 40W output power
  • Radiation immune magnetic feedback circuit: no use of optoisolators
  • Wide input voltage range of 18 to 40 V
  • High input transient voltage: 50 V for 1 second
  • Very low output noise
  • Protection features: short circuit/current limit, undervoltage lockout
  • Full performance over -55°C to +125°C military temperature range
  • Flanged and non-flanged case styles available
  • Fixed switching frequency of 525 kHz
  • Hermetic hybrid technology

Space-Level Characterizations:

  • TID performance to 100 krad(si) characterized for ELDRS
  • SEE characterized to 85 MeV/mg/cm2 with no dropouts, shutdowns, latch up or burn out
  • Guaranteed performance through the use of hardened semiconductor components, RLAT testing on non-hardened components, and analysis
  • Characterization is performed at both the component level and at the SVRTR Series hybrid converter level
  • All characterizations performed according to VPT’s DLA approved RHA plan per MIL-PRF-38534, Appendix G, Level R
