Part Number: TPS23754EVM-420 Hi experts,
My customer is trying to create a board that uses the TPS23754EVM-420 as a design reference. Could you please answer the following questions?
(1) In the data sheet, I think that the RJ45 and PoE power receiving…
Hi Harry,
The AUX circuit will be different for flyback converter and forward converter. The DS is based on forward converter. And your schematic is flyback.
TPS23754EVM-383 is forward reference design
TPS23754EVM-420 is flyback reference design
Part Number: TPS23754EVM-420 Other Parts Discussed in Thread: TPS23754 , TPS23730 Hi Team,
Our customer intends to use the TPS23754EVM-420 but just had some queries particularly on how it works with the transformer. The user guide says that a separate…
Part Number: TPS23754EVM-420 Other Parts Discussed in Thread: PMP22301 Hello,
We refer to TPS23754EVM-420 to designed a 30-Watt (24V/1.25A) PD based on the modification guideline in
this forum. It is working but with lower efficiency (maximum around 81…
Part Number: TPS23754EVM-420 Hi
We are working on designing a PoE Splitter, We require 5v 4.5A Supply on the Splitter side. We came across both PMP5818 and TPS23754EVM-420 design. What is the difference in both. Which one we have to pick up for reference…

by the way, if the transformer's size is not suitable to customer, example…
Part Number: TPS23754EVM-420 Other Parts Discussed in Thread: TPS23754 Hi team,
Looking at Figure 1 in TPS23754EVM-420 user's guide, there is TVS diode (D18) on the schematic.
According to TPS23754 datasheet 8.2.2.2, D18 is used for an additional…
Part Number: TPS23754EVM-420 Hi, Are the design files available for TPS23754EVM-420? Altium format would be ideal, but I will likely be able to import other formats. Thanks!
Hi Jimmy,
Thanks for reaching out!
The PoE can provide DC Power over same Category 5 twisted-pair cable that carries Ethernet data, like the below two pictures.
The power device (PD) TPS23754 has an internal MOSFET as hotswap and PWM controller. You…
