SI3460 Datasheet (Silicon Laboratories) - IEEE 802.3af PSE INTERFACE AND DC-DC CONTROLLER

SI3460, IEEE 802.3af PSE INTERFACE AND DC-DC CONTROLLER

The Si3460 is a single-port *48 V power management controller for IEEE 802.3af-compliant Power Sourcing Equipment (PSE).

Designed to minimize system cost and ease of implementation in embedded PSE endpoint (switches) or midspan (power injector) applications, the Si3460 operates directly from
