Product Introduction

Overview

The TPS23754PWPR-1 from Texas Instruments is a highly integrated Power over Ethernet (PoE) controller and DC/DC converter, designed to optimize power management in various applications. This device combines a PoE powered-device (PD) interface with a current-mode DC/DC controller, making it ideal for isolated converter topologies. It supports both IEEE 802.3at (PoE+) and 802.3af (PoE) standards, ensuring compatibility with high-power midspan power sourcing equipment (PSE).
