Connected LED Lighting with IEEE802.3bt Power Over Ethernet (PoE) Evaluation Module

Texas Instruments' TPS2372-4EVM evaluation module featuring Wurth Electronics components is ideal for IEEE802.3bt PoE PD applications

Image of Texas Instruments' Connected LED Lighting With IEEE802.3bt Power Over Ethernet (PoE) Reference Design Texas Instruments' TPS2372 evaluation module (TPS2372-4EVM-006) is built as a reference design for the TPS2372 IEEE802.3bt PoE PD controller, which is suitable for high power PoE PD applications such as LED lighting and modules. Texas Instruments and Wurth Electronics showcase this with the Power over Ethernet (PoE) evaluation module which supplies power and data over a single Ethernet cable to a connected LED lighting ballast. This evaluation module uses Texas Instruments' 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.

Features
