TPS23754PWP

Overview

The TPS23754PWP is a high-power, high-efficiency Power over Ethernet (PoE) interface and DC/DC controller designed for IEEE 802.3at (PoE+) and 802.3af standards. It integrates a powered device controller with an internal switch and a DC/DC converter. Key electrical parameters include a maximum current limit of 850 mA, a maximum on-resistance of 750 mOhms, and a maximum output power of 30 W. The device operates within a supply voltage range of 0 V to 57 V and supports a wide operating temperature range from -40°C to +125°C.

Feature Summary

• Integrates PoE interface control with a synchronous buck DC/DC converter in a single package.
• Supports both IEEE 802.3af and 802.3at Powered Device classifications.
• Features an internal low-on-resistance switch for efficient power delivery.
• Includes comprehensive protection mechanisms for robust operation.

Applications

• Wireless access points requiring PoE+ power injection
• IP security cameras and video surveillance systems
• VoIP telephones and communication endpoints
• Industrial IoT sensors and controllers

Procurement Notes

Verify the complete part number including the suffix 'PWP' to ensure the correct HTSSOP-20 package and tape-and-reel or tube availability as specified by Texas Instruments. Confirm that the procurement source provides official datasheets matching the TPS23754(-1)/56 specification. Ensure compliance with RoHS directives and check for any specific handling requirements related to the high-temperature rated components.

Selection Notes

Select this component when designing systems requiring integrated PoE classification and DC/DC conversion without external switches. It is suitable for applications needing up to 30 W of power with high efficiency. Consider the thermal performance of the HTSSOP-20 package for high-temperature environments. Compare against the TPS2375 series for lower power options if 30 W exceeds system requirements.

Part Context

This part belongs to the Texas Instruments TPS2375 family of PoE controllers. It is specifically engineered for high-power applications compared to the standard TPS2375. The device simplifies design by combining interface logic and power conversion, reducing component count and board space in modern networking equipment.

Replacement Considerations

Official substitutes include other members of the TPS2375 family such as the TPS23754PWPR for reel packaging variations. Verify pin-to-pin compatibility and electrical specifications before replacing. Consult the latest TI documentation for any obsolescence notices or recommended upgrades within the PoE controller portfolio.
