TPS23751PWP

Power Over Ethernet (PoE) Controllers Overview

The TPS23751PWP is a 16-pin HTSSOP integrated circuit combining an IEEE 802.3at PoE Powered Device interface with a current-mode DC-DC controller. It supports Type 1 (13W) and Type 2 (25W) power levels, operating within a 9.2V to 57V input range. The device features a minimum current limit of 850mA, typical inrush limiting of 140mA, and primary-side adapter priority for optimized efficiency across wide load ranges.

Power Over Ethernet (PoE) Controllers Feature Summary

• Integrates PoE PD interface and flyback DC-DC controller for high-efficiency power conversion
• Certified for Ethernet Alliance compliance and IEEE 802.3at standards
• Includes thermal shutdown and auto-retry fault response mechanisms

Power Over Ethernet (PoE) Controllers Applications

• High-efficiency synchronous flyback converters requiring 5A output at 5V
• PoE-powered devices needing optimized performance across wide load ranges
• Applications requiring certified IEEE 802.3at Type 1 and Type 2 power reception

Power Over Ethernet (PoE) Controllers Procurement Notes

Verify the complete part number including suffixes such as PWP or PWPR against official Texas Instruments documentation to ensure correct package type and tape-and-reel configuration. Confirm that the specific revision matches the required design specifications before procurement.

Power Over Ethernet (PoE) Controllers Selection Notes

Select this component when designing systems requiring integrated PoE classification and DC-DC control in a compact form factor. Ensure the application utilizes a flyback topology compatible with the internal current-mode controller and verify that the thermal management strategy aligns with the device's shutdown characteristics.

Power Over Ethernet (PoE) Controllers Part Context

This part belongs to the TPS2375x series of Power over Ethernet interfaces. It is distinct from the TPS23752, which adds sleep mode functionality, and the TPS23754, which supports higher power levels up to 30W. The TPS23751 focuses on standard Type 1 and Type 2 operation without advanced low-power sleep states.

Power Over Ethernet (PoE) Controllers Replacement Considerations

The TPS23752 serves as a functional substitute if sleep mode capability is required. For applications needing higher power density up to 30W, the TPS23754 is the appropriate alternative within the same family.
