SI3483 Overview
Description
The Si3483 is a power manager intended for use with the Si3459 Power over Ethernet (PoE) controllers for power management of up to 64 ports with three power sources. The Si3459 is capable of delivering over 30 W per port, which means that, in a 24or 48-port system, a very large power supply would have to be used to avoid overload.
