Description：

The RT3207 series of modules are designed to extract power from a conventional twisted pair Category 5 Ethernet cable, conforming to the IEEE 802.3af Power-over-Ethernet(PoE) standard.

The RT3207 signature and control circuit provides the PoE compatibility signature and

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

to 15W power to the port. The RT3207  provides a Class 0 signature.

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.

• RT3207 Product Selector

*At 25°C with VIN = 48V

** Maximum Output Power: means it not could be operated in continuous stage .only short-term of Boot up/Heavy loading

• Absolute Maximum Ratings

Note 1: Exceeding the above ratings may cause permanent damage to the product. Functional operation under these conditions is not implied. Maximum ratings assume free airflow.

• Recommended Operating Conditions

Note 1: With minimum load

     2: See Section Operating Temperature Range

      ** Extended use close to, or at the maximum operating temperature can reduce the life time of the device.

• Pin Description:

• DC Electrical Characteristics

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.
