  • Efficiencies in excess of 85% above 200°C
  • Vin: from 12V to 50V
  • Vout: from 0.1xVin to 0.9xVin
  • Synchronous mode available
  • Soft-start feature
  • Line regulation better than 1.5mV/V
  • Pout up to 280W (40V version) and 180W (50V version)
  • Short-Circuit Protection


  • Typical efficiency of Erebus-based DC-DC converters EREBUS40 with 4A max output Logarithmic

Applications

  • Distributed power architectures in aeronautics, aerospace, industrial and military electronic systems:
    • PoL (Point of Loads)
