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
