Part Number: TPS23751 Other Parts Discussed in Thread: PMP11254 , Hi Sir, I have question about TPS23751 PMP11254 schematic. May I know R36 improve current ramp in schematic, right? I can remove it?
Hi Akshay,
Thanks for reaching out to us!
1. VFO reduces switching frequency to lower the switching losses. But VFO also has higher requirement on transformer / coupled inductor to avoid flux density saturation since frequency drops. If the efficiency…
Hi Jordan,
HPA244EVM uses TPS2376 but with 5V/5A output. ( https://www.ti.com/tool/TPS2376HEVM )
You may consider to change the secondary side (including the transformer) to a 12-V case (e.g. www.ti.com/tool/PMP11254) . If you want sync FET you may consider…
Part Number: TPS23754-1 Other Parts Discussed in Thread: TPS23756 , PMP11254
Hi Sir,
we directly change TPS23754-1 from TPS23756, but found that +12v output has jitter problem.
hope learn from you, what parts of the schematic need to be modified?
as attached…
Part Number: TPS23751 Other Parts Discussed in Thread: PMP11254 , Dear Specialists,
My customer is considering TPS23751 and referring PMP11254.
They have a question about how to calculate Rff.
I'd be grateful if you could advise.

Hello,
Yes the output voltage can be whatever is required. The DCDC converter can be replaced with any DCDC converter that suits your project needs.
The TPS23731EVM-095 is a syncrhonous flyback. For more information on the types of flybacks in TI PoE…
Hello,
we are also using PMP11254 as the basis for a low cost TPS23751 design. We have also changed the transformer against LinkCom LDT8202-51R.
Question: What is the allowable input voltage range for adapter supply? PMP11254 is rather limited form 41…
Hello,
Please see the following paper for calculating components in a flyback:
Alternatively, the following reference design meets your exact needs: https://www.ti.com/tool/PMP11254
Either copy this design completely or use it as a guide. Thanks!

Part Number: TPS23751 Other Parts Discussed in Thread: PMP11254 , Hi Team,
My customer wants to use TPS23751 and refer our PMP11254 design. But they are concerning the EMI performance. Do we have the EMI test report that relates to TPS23751 could be shared…
Hi Gareth,
Thank you for your questions.
On the PSE side, we don't have a single port only PSE but the TPS23861 is recommended for single port up to 30W PSE applications. You can find a reference design PMP20588 where the TPS23861 is used in a single…
