Finding the Right Power Transformer for your PoE PD Design

A PoE Controller is used to negotiate power levels and control the isolated DC-DC circuitry inside of a product’s enclosure. With ever-increasing numbers of PoE controllers commercially available, finding the right power transformer for your PoE Powered Device (PD) design can be daunting. Fortunately, Pulse offers real time support and resources to help assist and simplify the task. When choosing a PoE PD transformer, there are several basic things to consider:

  • Power IC and topology to be implemented
  • Power Levels
  • Physical Size and Mechanical Restrictions
  • Number of Auxiliary and Secondary Outputs
  • Secondary and Auxiliary Output Voltages and Current

Once these general constraints are known, Pulse can leverage existing catalog designs and common platforms, as well as a team of experienced design and applications engineers to either help select an appropriate product or create a transformer that fits a customer’s specific technical and commercial requirements.
