AN313 Overview
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.
