Part Number: TPS2378EVM-105 Hello,
I have 2 questions about TPS2378EVM-105 schematic.
1. Center Tap Ground of Both side of Transformer(T1) are same. It looks not good for isolation.
Could you let me know why Grounds not separated? Is there any special…
Part Number: TPS2378EVM-105 Other Parts Discussed in Thread: TPS2378 I have interfaced TPS2378 with one of the POE port (Ethernet switch with POE port) . MCT1 (+) and MCT2 (-) are connected to bridge. Not interfaced any adapter ckt.
I am not able to get…
Part Number: TPS2378EVM-105 Other Parts Discussed in Thread: TPS2378 Hello all,
We currently have a design of PCB which uses the LM5073, which is now an obsolete part and we need to do some redesigning for a replacement PD chip. I have obtained the TPS2378…
Part Number: TPS2378 Other Parts Discussed in Thread: TPS2375EVM , I am attempting to use PoE to power my design (board powered by DCDC needing power from PoE) but the PD power shuts down when I connect the power out from the TPS2378EVM-105 to my design…
Part Number: TPS23758 Other Parts Discussed in Thread: TPS2378 , TPS23753AEVM-001 , TPS2378EVM-105 Hi Team,
I have a customer who is interested in using TPS2378 for their project, but they are using RJ45 with magnetic build in. Is there a way to connect…
Part Number: TPS2378 Hello
I use TPS2378 on our product, I measured output voltage at TPS2378 (between VDD and RTN pins) and inrush current between PSE (PoE injector) and our device. The ramp up time of the output voltage is very fast, I've measured typically…

Hi there,
We are designing an active Type-II Class 4 PoE splitter and it is based-on TPS2378EVM-105 as shown below.
Some notes about the schematics;
Although APD(2) pin for TPS2378 seems floating, it is tied to RTN(5) pin via 10k…
Hi,
Thank you for your question.
I noticed the Bob Smith termination is incorrect. I recommend the customer add 10nF cap in series with each of the R29/R30/R31/R32 resistors. They can follow the TPS2378EVM-105 schematic as an example, and these are the…
Part Number: LM3414HV Other Parts Discussed in Thread: TPS2378EVM-105 , , LM3414 I am building a POE LED driver circuit. I am feeding the LM3414HVMREVAL board from the TPS2378EVM-105 eval board supplying 48v from POE. How do I set the LM3414HV to output…
Hi Thomas ,
When you say TPS2384 doesn't establish PoE connection with TPS2378EVM-105, do you mean the detection failed? Have you tried connecting TPS2384EVM to TPS2378EVM-105? Thanks.
Best regards,
Penny
