SI3480 Overview
The Si3480 is a power manager intended for use with the Si3452 Power over Ethernet (PoE) controller. The Si3480 enables the use of a smaller, lower cost, and more efficiently-utilized power supply in an unmanaged PoE Power Sourcing Equipment (PSE) system. The Si3452 is capable of delivering over 30 W per port, which means that, in a typical 8-port system, a 240 W power supply would have to be used to avoid overload.
