Hi Gordon,

Unfortunately we do not have this excel file of slua535.

For a reference, you can see the UCC2897A excel file. I have attached here. Hope it is useful for you.sluc662a.zip

For more information about this topology, you can see below link under UCC2897A.

Dear Sir,
Your Execel file is very useful for me but TI FAE suggest TPS23754 to design for forward architecure(PMP9563_RevA_SH2.SchDoc).
UCC2897 archecture is different with TPS23754.
Could you share your calculation tool of Excel file??

Dear Sir,

The tool (PoE_PD_EfficiencyCalculator.xlsx) is only calculate efficiency simplly.

Do you use the format of "SLUC662.xlsx" to caluculate TPS23754?

Hi Gordon，

TPS23754 is not the same as UCC2897A, you can not use SLUC662. for a reference , you can see the reference design PMP6659, which is used the series of TPS23754.
Can you please create a new post with TPS23754? In this way you can find the right person to answer you, thanks.
