Silvertel Ag5810 PD module

Silvertel has announced the IEEE 802.3bt compliant Ag5810 PD (powered device) module for Power over Ethernet (PoE) solutions. Aimed at developers of Ethernet equipment requiring up to 60 W of power, such as LED lighting, PTZ cameras, WiMAX access points, door entry systems, digital signage and thin client terminals, the product is a suitable drop-in IEEE802.3bt solution.

The product is a Type 4, Class 7 PD, which provides 60 W of power by displaying the correct class pulses to an IEEE802.3bt PSE. A complete high-efficiency DC-DC converter is included and generates a nominal 12 or 24 V output, which can be programmed down to 11 V or up to 30 V; this is especially useful for applications requiring the inclusion of battery chargers. Additional features include 1500 V isolation (input to output), overload, short-circuit and thermal protection.

Requiring just a few external components, the product is easy to use and occupies a minimum of PCB real estate. Evaluation boards are also available, as well as a range of application notes.
