In the industry standard half brick footprint, the conservatively rated PAH series of 29W to 451W DC-DC converters are available with output voltages of 2.5V to 48V. This large series of regulated power modules features wide input ranges with both 24V and 48V nominal inputs, remote sense, output adjustment and remote on/off.

Key Market Segments & Applications

  • Base Station Power Amplifiers
    Bus converters for Distributed Power Architectures

Benefits

  • Reduces need for custom modules
  • Replaces 3/4 or Full Brick Power Modules
  • Reduced component count, increased MTBF
  • Suitable for remote & central office applications
