Description：

The RT7640 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 RT7640 signature and control circuit provides the PoE compatibility signature and

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

to30W 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.
