  • Description

    The RT7650 series of modules are designed to extract power from a conventional

    twisted pair Category 5 Ethernet cable, conforming to the IEEE 802.3af and IEEE 802.3at    Power-over-Ethernet(PoE) standard.

    The RT7650 signature and control circuit provides the PoE compatibility signature and

    power classification required by the Power Sourcing Equipment (PSE) before applying up

    to 30W power to the port.

    The DC/DC converter operates over a wide input voltage range and provides a regulated

    output. The DC/DC converter also has built-in short-circuit output protection.

  • Power Classification
  • The RT7650 classification is fixed at Class 4, this means that an IEEE802.3at Type 1 or an IEEE802.3af PSE will default to Class 0. However an IEEE802.3at PSE will recognise the Class 4 as a Type 2 PD.

    Note 1: Typical figures are at 25°C with a nominal 48V supply and are for design aid only. Not Guaranteed

         2: The output ripple and noise can be reduced with an external filter, see application note.

         3: Continuous short circuit duration is applicable at 25'C ambient temperature in free air. At higher temperatures or with restricted

            airflow (e.g. in a sealed enclosure) the duration will need to be limited to avoid overheating.
