Overview
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.
The Si3406x family integrates the required diode bridges and transient surge suppressor, thus enabling direct connection of the IC to the Ethernet RJ-45 connector.
The switching power FET and all associated functions are also integrated.
The integrated, current mode controlled switching regulator supports isolated or non-isolated flyback and buck converter top...
