Is there a design calculator (Excel) which can help in the design, like the one you have for LM5155…
Part Number: PMP20220 Hello sir
i had selected PMP20220 design for my application but sir my output ethernet port is not getting up i am getting an output voltage of 5V but ethernet port is not working .
Part Number: TPS23751 Other Parts Discussed in Thread: PMP20220 , PMP11254 , TIDA-00617 hi team,
do we have a deign guide on the regarding power ,Vin, Vout, frequency ？ thanks~
Patrick,
You can add more capacitance to reduce the ripple, but it won't help much with the switching spikes.
The most effective way to reduce the ripple and spikes is to add a second stage filter. PMP20220 shows an example.

We plan to use TPS23751 for POE power supply design. Our design needs to meet 12W output, meet the protection requirements of common mode 6KV and differential mode 2KV. Our design refers…
Hey Fabian,
1. When I look at the provided scope shot, to me trace #3 shows a voltage on VDD_VSS which makes me conclude the surge is affecting this input. How do you understand that image?
For the diode, would the below image not work? This would block…
