EREBUSŪ

50V non-isolated buck DC-DC converter technology

 

 

EREBUS® is CISSOID’s technology allowing to build High Temperature, High Efficiency Step-down DC-DC Converters on the basis of CISSOID’s two-chip set MAGMA -HYPERION  and two  power MOSFETs.

Typical performances

  • Operating junction temperature: -55°C to +225°C
  • 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

 

Application

  • Distributed power architectures in aeronautics, aerospace, industrial and military electronic systems:
    • PoL (Point of Loads)
    • PDU (Power Distribution Units)
  • SMPS power supplies in down-hole tools such as MWD and LWD equipment

If you need support for your high temperature power supply design, just contact Cissoid.
