Description

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.

In need of an IEEE802.3bt-ready PSE controller? Check out the TPS23881.

Features
  • IEEE802.3bt Ready
  • PD 51W Class 6 Power Level
  • Minimal Standby Power Consumption of 181 mW
  • Automatic Maintain Power Signature
  • IP-Addressable Board for Network Connected
