Procurement Notes

Verify the exact suffix 'PWP' against the manufacturer's official datasheet to confirm the HTSSOP-20 package variant. Ensure compatibility with the 0 V to 67 V input range and 12.95 W power rating for your specific design requirements. Cross-reference the RoHS status and humidity sensitivity classification before finalizing procurement.

Selection Notes

Select this component when designing systems requiring integrated PoE PD control and DC/DC conversion under the 802.3af standard. The HTSSOP-20 package offers a compact footprint suitable for space-constrained layouts. Consider the 405 mA current limit and 1 Ohm on-resistance when sizing downstream components and thermal management solutions.

Part Context

This part belongs to the TPS23770 series of integrated PoE controllers. It serves as a complete solution for powering networked devices over Ethernet cables. The series is designed to simplify system architecture by combining interface logic and power conversion capabilities into a single IC, reducing component count and board space.
