TPS23754PWPR-1

Overview

The TPS23754PWPR-1 is an IEEE 802.3at PoE interface and isolated converter controller designed for powered devices. It supports input voltages from 0 V to 57 V with a maximum current limit of 850 mA and a typical on-resistance of 750 mΩ. The device operates within a temperature range of -40°C to +125°C and is housed in a 20-HTSSOP package. It enables power delivery up to 30 W, integrating both PoE interface logic and DC/DC control functions for high-efficiency isolated topologies.

Feature Summary

Integrates IEEE 802.3at PoE interface logic with isolated DC/DC converter control
Supports high-efficiency power topologies for powered devices
Provides complete power management solution for up to 30-W applications

Applications

IEEE 802.3at Powered Device implementations
Isolated DC/DC converter designs for PoE endpoints
High-efficiency network interface power supplies

Procurement Notes

Verify the specific suffix '-1' indicates the isolated converter variant distinct from the standard TPS23754PWPR. Confirm the HTSSOP-20 package marking matches project requirements. Ensure supply chain sources provide official Texas Instruments documentation to validate component authenticity and revision status prior to integration.

Selection Notes

Select this component when designing IEEE 802.3at compliant powered devices requiring integrated isolation control. The device combines interface detection with DC/DC regulation, reducing external component count. Consider the 850 mA current limit and 750 mΩ on-resistance for power budget calculations. The wide operating temperature range suits industrial environments.

Part Context

This part belongs to the Texas Instruments TPS2375x family of PoE controllers. Unlike the non-isolated TPS2375PWR-1 or the standard TPS23754PWPR, the -1 suffix denotes the version optimized for isolated converter architectures. It shares the 802.3at standard compliance but differs in internal control topology compared to non-isolated counterparts.
