DPA and IBA front ends

DPA and IBA front ends

Eaton’s digitally-controlled AC/DC front ends are designed for high-availability cloud computing, high-performance servers, routers and switches utilizing Distributed Power Architectures (DPA) or Intermediate Bus Architectures (IBA).

Eaton’s library of high-efficiency topologies includes fully digitally-controlled, bridgeless-boost PFC stages combined with highly-optimized LLC converters and synchronous rectifiers. These proven topologies can be leveraged to quickly develop cost effective, modified and custom solutions.

Atf-1200 platnum efficiency dpa/iba front ends ATF-1200-Y-P-3.3 AC/DC front ends (pictured above) provide up to 100 amps of 12V and a 3.3V standby output. Digitally-controlled topologies and advanced thermal-management techniques deliver up to 95.5% efficiency and a power density of 29 watts per cubic inch. Additional features include:

  • 80-plus platnum certified efficiency
  • 90 -264 VAC input with power-factor correction
  • Parallel operation with active digital current sharing
  • I2C interface for control, monitoring and programming with PSMI protocols
Cost-effective custom solutions

Eaton can leverage a broad array of high-efficiency topologies and standard products to reduce development and unit costs and accelerate time to market for modified and custom AC/DC and DC/DC power supplies for distributed power and intermediate bus architectures:

  • Low-profile power shelves that fit 1U height constraints
  • Complete rack and cabinet power systems from kilowatts to megawatts
  • Backplane or front-mounted, single or three-phase-input connectors
  • Digital monitoring and management protocols incluing PMBUS

48v power architecture solutions Eaton’s 48Vout rectifiers feature high-efficiency topologies that reduce energy costs and facilitate meeting aggressive carbon footprint reduction targets. Additional features include:

  • Broad range of datacom / telecom rectifiers from 900 to 5800 watts
  • Efficiencies up to 96% with 0.99 power factor
  • Turnkey DC power solutions include shelves, racks and cabinets
