Description

VPT’s SV Series of DC-DC converters are mission proven in systems launching for LEO, MEO, GEO, and deep space missions. Qualified to MIL-PRF-38534 Class K on DLA SMDs, these  off-the-shelf units 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 to create a light weight, extremely efficient, space-ready power system.

Packing 20W in a miniature, lightweight case, the SVHF DC-DC converter is guaranteed radiation tolerant including ELDRS for the longevity of your space mission.

Features

  • Single outputs of 2.5V, 3.3V, 5V, 12V, 15V and 28V
  • Up to 20W output power
  • Fault tolerant design with radiation immune magnetic isolation technology – no optoisolators
  • Extra-wide 15V to 50V input range per MIL-STD-704, transients to 80V for 1 sec
  • Extremely low profile (.330 inches) and light weight (24/28g) fully hermetic packaging
  • Wide case temperature operation of -55°C to +125°C with full performance over temperature range
  • Flanged and non-flanged case styles available
  • Fixed switching frequency

Space-Level Characterizations

  • Characterized and guaranteed to 30krads (Si) per VPT’s RHA plan specified per MIL-PRF-38534, Appendix G, Level P with 2x margin
  • Characterized and tested for TID (total ionizing dose) at HDR (high dose rate) and LDR (low dose rate — ELDRS) per VPT’s RHA plan
  • SEE characterized for no destructive events up to LET = 44 MeV-cm2/mg including SEB, SEL, SEGR, and SEFI. No dropouts, shutdowns, latch up or burn out. Up to 85 MeV-cm2/mg also available.
  • Characterization and testing is performed at the critical semiconductor component piece-part level (RLAT) from traceable semiconductor lots
  • Characterization and testing also performed on the SVFL Series hybrid converter produced from the same traceable semiconductor lots evaluated during RLAT

Compliances and Certifications

  • Available to MIL-PRF-38534 Class K on DLA SMD# 5962-11218
