Silicon Labs SI3404-A-GM

控制器（PD），DC/DC15.4 W802.3at（PoE）

Overview

Silicon Labs Si3404 Power Over Ethernet (PoE) Powered Device (PD) is a highly-integrated, IEEE 802.3at Type 1-compliant, Pulse-Width-Modulated (PWM) Switching Regulator. The Si3404 integrates all power management and control functions required in a Power-over-Ethernet application. The Si3404 PD converts the high voltage supplied over a 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 (Bill of Materials) cost, and enables the use of low-cost external components while maintaining high performance.
