Overview

The Ag9205 is a PoE module designed for higher efficiency than standard Silvertel products. The module extracts power from a conventional twisted pair Category 5 Ethernet cable, conforming to the IEEE 802.3af Power over Ethernet (PoE) standard. This is a total solution, including a 1.5kV isolation barrier between the input and output. The Ag9205S has been specifically designed to give more power at 5V output voltage than standard Ag9705 series parts.

Description

The Ag9200 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 Ag9200 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 Ag9200 is compatible with Class 0 to Class 3 equipment. The high efficiency DC/DC converter operates over a wide input voltage range and provides a regulated low ripple and low noise output. The DC/DC converter also has builtin overload and short-circuit output protection.
