Part Number: TPS23754EVM-420 Dear All:
I want to modify TPS23754EVM-420 output voltage from 5V to 4.5V, please help to let me know how can I do?
Thank you!!
Part Number: TPS23754 Other Parts Discussed in Thread: , PMP11254 , TPS23751 Dear Sir,
I want to re-design a fly-back POE circuit of TI SLVU301.pdf(TPS23754EVM-420 EVM).
Vout=5V => 12V , Fsw=250KHz => 480KHz, Could you teach me where components need…
Other Parts Discussed in Thread: TPS23754EVM-420 Hi Darwin,
As per TPS23754EVM-420, 24V O/P design we have designed PD .
But instead of 24V we are getting 10V approximately and output voltage too noisy with more spikes.
Kindly check the design…

One more question,
Now we are looking to change RJ45 connector and External transformer solution instead modular jacks .If you any suggestion…
Part Number: TPS23754EVM-420 Hi
We are referring TPS23754EVM-420.
In this board, ETH1-230LD is used for PoE Magnetics.
However I don't have idea this EVM is made for assuming gigabit speed (1000base).
By referring BOM in TPS23754EVM-420, can…
Part Number: TPS23754EVM-420 Other Parts Discussed in Thread: TPS23754 , Hi,
Iam planning to design 24V/1.25A POE design using TPS23754 for our project.
I have searched several TI design but could not find 24V/25W, then i have followed suggestion…
Hi,
Thanks for reaching out.
Here are the comments on the design:
1. Remove C5.
2. Use Vss for input ground. And please separate VSS and GND_POE.
3. DT connects to GND_POE through a resistor.
4. Change the transformer polarity on the primary…

I have questions about TPS23754EVM-420 Schematic (slvu301)
Should I use diode (D13,D14) ? Could you pls tell me the reason.
Hi Michael,
I tested on TPS23754EVM-420, the T2P pin will be low (active low) when you use Option 2 adapter and APD pin is above threshold. Can you show circuit with T2P connection?
Best regards,
Diang
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 des…
