Connected LED Lighting With IEEE802.3bt Power Over Ethernet (PoE) Reference Design
TIDA-01463
Overview
This Power over Ethernet (PoE) reference design supplies power and data over a single Ethernet cable to a connected LED lighting ballast. This reference design uses TI's TPS2372-4 PoE powered device (PD) interface, LM3409 buck controller, LM5165 buck converter, TPS62740 buck converter, TM4C1292NCPDT microcontroller (MCU), TPD4E05U06-Q1 ESD protection device, and DP83822I Ethernet PHY to provide power to the LED light remotely controlling the brightness and dimming parameters of the LED light while connected to the network.
