Meeting IEEE802.3at this device is the latest in the Ag5300 range which also includes 12V and 24V versions (up to 30W). Aimed at developers of Ethernet equipment requiring up to 20W of power, such as, IP cameras, PTZ cameras, WiMAX access points, door entry systems, digital signage and VoIP phones and terminals.
The Ag5305 provides a low cost drop-in IEEE802.3at solution. Ag5305 is a Class 4 PD, which provides up to 20W of power by displaying the correct class pulses to a IEEE802.3at PSE. A complete high efficiency DC-DC converter is included, that generates a nominal 5V output, which can be programmed down to 4.4V, or up to 5.8V.
Additional features include 1500V isolation (input to output), overload, short-circuit and thermal protection. Requiring just a few low cost external components, Silvertel has provided another product which is low cost, easy to use, and occupies a minimum of PCB real estate. Ag5300 evaluation boards are also available, as well as a range of application notes, backed by Silvertel’s class-leading technical support team.
