Barracuda™ Series DC-DC Converters

ABB's Barracuda series of DC-DC converters are a new generation of DC-DC power modules designed to support intermediate bus applications where multiple low voltages are subsequently generated using point-of-load (POL) converters, as well as other applications requiring a tightly-regulated output voltage. With an input voltage range of 36 VDC to 75 VDC in a DOSA-standard quarter brick, the converter incorporates digital control, synchronous rectification technology, and a fully-regulated control topology. This leads to lower power dissipations, so for many applications a heat-sink is not required.

Features
  • Wide input voltage range: 36 VDC to 75 VDC
  • Low output ripple and noise
  • Constant switching frequency
  • Positive remote ON/OFF logic
  • Output overcurrent/voltage protection
  • Over-temperature protection
  • Tightly-regulated output voltage
  • Wide operating temperature range (-40°C to +85°C)
  • Industry-standard quarter brick: 58.4 mm x 36.8 mm x 11.7 mm
Applications
  • Distributed power architectures
  • Intermediate bus voltage applications
  • Servers and storage applications
  • Networking equipment including Power over Ethernet (PoE)
  • Fan assemblies other systems requiring a tightly regulated output voltage
