Active PoE PD controller with integrated DC-DC
The TPS23750PWP is a single-channel Power over Ethernet Powered Device (PD) controller with an integrated DC-DC converter, compliant with IEEE 802.3af. It delivers up to 12.95 W to the load, covering the full Class 0-3 power range defined by the standard. The internal switch (Internal Switch(s): Yes) eliminates the need for an external hot-swap FET, reducing BOM count and board area. The controller operates from a 0 V to 67 V supply, covering the full PoE input range including legacy midspan injectors.
Thermal and package considerations for layout
The 2 mA supply current (Current - Supply: 2mA) is the controller's own draw; the 12.95 W output power is delivered to the load through the integrated DC-DC stage. Layout should keep the switching node short and the feedback path away from the inductor to avoid noise coupling.
Active production and compliance posture
Texas Instruments lists the TPS23750PWP as Active (productStatus: Active) and ROHS3 Compliant.
