Procurement Notes

Verify the specific suffix 'PWPR' corresponds to the tape-and-reel packaging variant when ordering. Confirm that the HTSSOP-20 package dimensions align with your PCB footprint requirements. Ensure compatibility with IEEE 802.3at Type 2 power sourcing equipment specifications before finalizing procurement.

Selection Notes

Select this component for applications requiring integrated PoE interface and DC/DC control in a single package. It is suitable for designs needing support for up to 25W power levels under IEEE 802.3at standards. Consider its thermal management capabilities and auto-retry features for robust operation in network environments.

Part Context

The TPS23756 belongs to the TPS2375x family of high-efficiency PoE controllers from Texas Instruments. This series addresses the needs of modern network devices requiring higher power budgets than traditional 802.3af standards allow. The PWPR designation indicates the surface-mount version packaged in tape and reel for automated assembly processes.

Replacement Considerations

Public confirmed substitute part numbers include TPS23754 and TPS23757.
