TPS23750PWPR

Power Over Ethernet (PoE) Controllers Overview

The TPS23750PWPR is an integrated IEEE 802.3af Powered Device (PD) and DC/DC controller manufactured by Texas Instruments. It supports a wide input voltage range of 0V to 57V, with an operating voltage window of 36V to 57V after startup. The device features a current limit of 405mA to 495mA and includes an internal buck converter capable of delivering up to 2A at 5V or 2.5A at 3.3V. It operates within a temperature range of -40°C to +85°C and is housed in an 8-pin TSSOP package.

Power Over Ethernet (PoE) Controllers Procurement Notes

Verify the suffix 'PWPR' confirms the tape-and-reel packaging format required for automated surface-mount assembly. Ensure the component meets RoHS compliance standards as indicated in official documentation. Confirm the specific grade matches the intended industrial or commercial temperature requirements before finalizing procurement orders.

Power Over Ethernet (PoE) Controllers Selection Notes

Select this component when designing compact PoE endpoints requiring integrated power management. It eliminates external discrete components for the PoE interface and primary-side regulation. Suitable for applications needing strict adherence to IEEE 802.3af standards with minimal bill-of-materials complexity.

Power Over Ethernet (PoE) Controllers Part Context

This part belongs to the TPS2375x family of PoE controllers from Texas Instruments. It serves as a complete solution for powering Ethernet devices without separate PSE negotiation logic. The family offers various pin counts and power capabilities to suit different form factors and power budgets.

Power Over Ethernet (PoE) Controllers Replacement Considerations

Direct substitutes include TPS23750PWP and TPS23750PWPG4. Verify pin compatibility and thermal performance when transitioning between reel and tube packaging variants.
