SVLFL2800S DC-DC Converter

VPT’s SVL 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.

With no stacked capacitors, the SVFL family of DC-DC converters utilize well controlled under-voltage lockout circuitry to eliminate slow start-up problems. Current sharing enables parallel operation of up to five units for 5x power output.

 

Features:

  • Single output options of 3.3V (66 W), 5V (100 W), 12V (110 W), and 15V (120 W)
  • Wide input voltage range: 16V to 40V continuous, 50V transient
  • Continuous operation over full military temperature range of -55°C to +125°C with no power derating
  • Very low output noise
  • Parallel up to 5 units with current sharing
  • Output voltage trim up +10% or down -20%
  • Radiation immune magnetic feedback circuit
  • No use of optoisolators
  • Undervoltage lockout
  • Current limit protection/short circuit protection
  • Low profile (3.005″ x 1.505″ x 0.400″) and light weight (86g) hermetic packaging with industry standard pinout. Standard and optional side-flanged versions available.

Space-Level Characterizations:

  • Guaranteed TID performance to 60 krads (Si) including ELDRS.
  • SEE performance to 85 MeV/mg/cm2 . Transients are fully characterized for cross section and magnitude.
  • Worst-case analysis, stress, radiation, reliability reports available.

Compliances and Certifications:
