TPS23750PWP

Power Over Ethernet (PoE) Controllers Overview

The TPS23750PWP is a third-generation Power-over-Ethernet (PoE) device from Texas Instruments that integrates an IEEE 802.3af Powered Device (PD) controller with a primary-side DC/DC pulse-width modulation controller. Housed in a TSSOP-8 PowerPad package, it features an internal 0.7-ohm FET to minimize heat dissipation. The device supports isolated and nonisolated power supply topologies, including flyback, forward, and nonsynchronous low-side buck designs. Switching frequency is configured via an external resistor, and the inrush current limit is set at 140 milliamps to facilitate PD startup.
