Si3406x Family Data Sheet
Fully-Integrated IEEE 802.3-Compliant POE+ PD Interface and High-Efficiency Switching Regulators with Sleep, Wake, and LED Drive
The Si3406x family integrates all power management and control functions required in a Power-over-Ethernet Plus (PoE+) powered device (PD) application. These devices convert the high voltage supplied over the 10/100/1000BASE-T Ethernet connection to a regulated, low-voltage output supply. The optimized architecture of this device family minimizes the solution footprint and external BOM cost and enables the use of low-cost external components while maintaining high performance.
