Hi Frank,
For a 12V output Class 3 design, please refer to PMP4679 which uses the TPS23750 PoE PD. Please let me know if this is not sufficient or if you have any additional questions.

Hi Tateo,
Yes the Rz will affect the crossover. It will also affect the gain. I think the best approach is to design similar to our EVM or TI Designs which use common PoE output voltages and are known working DCDC designs.
EVM can do 5V or 3.3V with…
And I am also checking for anything that specifically utilizes the TPS23750 controller. We do not have anything close enough to your requirements online. The closest we have is the 12V@0.95A non-isolated Buck topology ( www.ti.com/.../PMP4679) .
Part Number: TPS23753 TPS23753 can also do the following applications ?? (TPS23750 non-isolated)

Hello Takahiko-san, We do not have a reference design with the TPS2375; however, the closest we have is a non-isolated reference design with the TPS23750 with 12V, 0.95A output: www.ti.com/.../PMP4679
The TPS2750 is a derivative of the TPS23275 that includes…
You are on the right track. The LM5072 (application #4) could work with some adjustments for output voltage (C16, R12) as could PMP4679 ( http://www.ti.com/tool/pmp4679 ). You could also use something like that shown in ( http://www.ti.com/general/docs/lit…
Hi PAN-M,
Have you seen the PMP4679? This is a 12V 0.92A buck topology for PoE PD applicaitons. Please see below gerber files.

Please see the PMP4679 reference design http://www.ti.com/tool/pmp4679 which is available on the TPS23750 product page. C9-C12 values will change as will L2. The current through R10 produces a voltage proportional to the FET and inductor switching current…
Hello Cody,
Yes the TPS23730 can be used in a buck application.
We do not have any reference designs in that topology at this time. however, you can look at some of our other Poe_PD's + DCDC controllers in a buck application to help you get you started…
