Other Parts Discussed in Thread: TPS23731
Please help to suggest a possible solution for a smaller board/simpler circuit for PMP4909 reference design. I have reposted the customer's full inquiry below to explain it further.
"I am using an evaluation board you have called "PMP4909" and I want to know if a part of the schematic can be removed as I don't need it in my application. See attached image.
In the image above, I would like to keep the red box as that will be the power input for my application. I would like to remove the blue and orange area as I believe they are for connecting voltage directly, I will not have this need for my application and therefore I would like to remove it from the schematic if possible
If the POE input is supposed to be DC or AC? I do assume its DC but its my first time working with POE and I'm not sure how to connect the POE port to this schematic.
Since this is an evaluation board, is there any way I can make this board smaller but still keep parts on the top side of the PCB?
I know this is an old IC but if you can suggest any other newer IC's that can provide the same output of 12v 30W Class 4 POE+ which have a simpler schematic then please do suggest them as I am trying to make this design as small as possible and having a more integrated IC would help greatly."
Thank you so much.
