48 V-to-POL Power Stamp

The MAIN and SATELLITE Power Stamp are isolated DC-DC converter that converts a 48V or 54V bus voltage into a low voltage suitable for typical server’s motherboard subsystems.

Specifications

  • Over 94% efficiency at 1.8Vout
  • Over 91% efficiency at 1.0Vout
  • Up to 140W continuous output power / 200W peak
  • Up to 70A continuous output current / 100A peak
  • Wide 40V to 60V input voltage range
  • Power density exceeding 300W/in3

Features

  • Parallelable with automatic phase shedding
  • Flat efficiency curve over wide load ranges
  • Source and sink mode for fast transient response
  • Isolated power train
  • Secondary side fully digital control
  • PMBUs with configurable AVS or Intel SVID interface
  • Industry standard SMT package
  • Reference designs for selected applications
