Si3404 Data Sheet
Fully-Integrated IEEE 802.3 Type 1-pliant POE PD Interface and High-Efficiency Switching Regulator with pact Footprint
The Si3404 integrates the power management and control functions required in a Power-over-Ethernet (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 minimizes the solution footprint and external BOM cost and enables the use of low-cost external ponents while maintaining high performance. The Si3404 integrates a transient surge suppressor. The switching power FET and associated...
