Key Features
- IEEE 802.3af compliant PoE PD interface with integrated detection and classification eliminates external PoE front-end circuitry
- Integrated current-mode PWM controller supports flyback and forward DC-DC topologies from a single 48V PoE supply
- Up to 67V input voltage rating accommodates high-power PoE++ scenarios and transient overvoltage protection requirements
Applications
The TPS23750PWPR is used in PoE-powered IP phones, wireless access points, and network security cameras where the Ethernet cable provides both data and up to 15.4 W of power. By integrating the PD interface and switching controller, it simplifies the power conversion stage for IP intercoms, smart sensors, and building automation controllers. Designers of industrial IoT devices also use it to enable single-cable power and data delivery in factory floor deployments.

Frequently Asked Questions
Is the TPS23750PWPR compliant with the IEEE 802.3af PoE standard?
Yes, the TPS23750PWPR is fully compliant with IEEE 802.3af, supporting the required signature detection, classification, and inrush current limiting needed to be recognized and powered by a standard PoE power sourcing equipment (PSE) switch.
What is the input voltage range of the TPS23750PWPR?
The TPS23750PWPR operates from a nominal 48 V PoE supply with a maximum input voltage rating of 67 V, providing margin for transient overvoltages present on Ethernet cables in industrial and enterprise network environments.
What DC-DC converter topologies does the TPS23750PWPR support?
The integrated PWM controller in the TPS23750PWPR supports current-mode flyback and forward converter topologies, which are the most common architectures used for isolated DC-DC conversion in PoE powered devices requiring output voltages of 3.3 V, 5 V, or 12 V.
What package does the TPS23750PWPR come in?
The TPS23750PWPR is available in a 20-pin TSSOP (Thin Shrink Small Outline Package), which provides a compact surface-mount footprint suitable for space-constrained PoE device PCBs used in IP phones and wireless access points.
What are alternatives to the TPS23750PWPR for PoE PD applications?
Comparable PoE PD controller alternatives include the TPS23753A and TPS23756 from Texas Instruments for higher power classes, as well as the LTC4267 from Analog Devices and the AG9205S from Silvertel, all supporting IEEE 802.3af PD interface functions with integrated switching controllers.
