TPS23751PWPR

Power Over Ethernet (PoE) Controllers Overview

The TPS23751PWPR is a 16-pin integrated circuit combining an IEEE 802.3at PoE Powered Device interface with a current-mode DC-DC controller. It supports Type 1 (802.3af) and Type 2 (802.3at) standards, delivering up to 25W. Key electrical parameters include a maximum input voltage of 57V, minimum operating voltage of 9.2V, typical inrush limit of 140mA, and minimum current limit of 850mA. The device features programmable switching frequency, thermal shutdown, auto-retry fault response, and primary side adapter priority.

Power Over Ethernet (PoE) Controllers Feature Summary

• Integrates PoE PD interface and flyback DC-DC controller for high efficiency across wide load ranges
• Supports IEEE 802.3at Type 2 and Type 1 standards with programmable switching frequency
• Includes thermal shutdown, auto-retry fault response, and primary side adapter priority

Power Over Ethernet (PoE) Controllers Applications

• High-efficiency synchronous flyback converters for PoE applications
• Power over Ethernet powered devices requiring integrated control
• Designs optimized for wide load range efficiency

Power Over Ethernet (PoE) Controllers Procurement Notes

Verify the package type matches HTSSOP-16 requirements. Confirm the suffix 'PWPR' indicates tape-and-reel packaging. Ensure compatibility with IEEE 802.3at Type 2 specifications if higher power is needed. Check that the operating temperature range meets system constraints. Validate pinout against schematic designs before integration.

Power Over Ethernet (PoE) Controllers Selection Notes

Select this component when integrating PoE interface and DC-DC conversion into a single solution. It is suitable for applications requiring high efficiency at varying loads. Consider the 16-pin HTSSOP package for space-constrained designs. Evaluate the need for programmable switching frequency to optimize EMI performance. Compare with TPS23752 if sleep mode functionality is required instead.

Power Over Ethernet (PoE) Controllers Part Context

Part of the Texas Instruments TPS2375x series, designed for Power over Ethernet applications. It combines PD interface and DC-DC control to simplify design. The series supports multiple IEEE standards. This specific model focuses on Type 2 support without sleep mode features found in other variants.

Power Over Ethernet (PoE) Controllers Replacement Considerations

TPS23752 offers similar functionality but includes sleep mode features and uses a 20-pin package. Verify pin compatibility and feature requirements before substitution.
