AN313 - USING THE Si3400 AND Si3401 IN HIGH POWER APPLICATIONS
AN313 USING THE Si3400 AND Si3401 IN HIGH POWER APPLICATIONS 1.
Introduction Emerging Power over Ethernet (PoE) applications, such as multi-band and 802.11n access points, often require more power than the 12.95 W specified by the IEEE 802.3af.
This application note outlines how to use the Si3400 and Si3401 to support powered device (PD) applications over 15 W output, which corresponds to www.DataSheet4U.com about 20 W of input power from the PSE.
The current standard for Power over Ethern
AN313 Features
* an increased hot swap switch current limit of 470 mA (minimum). This allows the Si3401 to support 14 to 16 W applications with a small number of BOM modifications and by selecting an appropriate power supply topology. www.DataSheet4U.com Si3401-EVB and Si3401ISO-EVB application boards are available
