Manufacturer: Texas Instruments

Overview: Product Folder Order Now Technical Documents Tools & Software Support & Community Reference Design TPS23754, TPS23754-1, TPS23756 SLVS885I – OCTOBER 2008 – REVISED DECEMBER 2017 TPS2375x IEEE 802.

This datasheet includes multiple variants, all published together in a single manufacturer document.

General Description

The TPS23754 and TPS23756 devices have a combined power-over-ethernet (PoE), powereddevice (PD) interface, and current-mode DC-DC controller optimized specifically for isolated converters.

The PoE interface supports the IEEE 802.3at standard.

The TPS23754 and TPS23756 support a number of input voltage ORing options including highest voltage, external adapter preference, and PoE preference.

Key Features

  • Powers up to 30-W (Input) PDs.
  • DC-DC Control Optimized for Isolated Converters.
  • Supports High-Efficiency Topologies.
  • Complete PoE Interface.
  • Enhanced Classification per IEEE 802.3at With Status Flag.
  • Adapter ORing Support.
