Hi Diang

I wonder why the checklist is based on TPS23730RMT but not TPS23751PWPR? Or what parts could I refer to? Thanks.

Hi Vince,

Sorry that we do not have a full check list for TPS23751.

Sorry that the PoE team has traveling and multiple works in list recently. Please expect a delay on the E2E reply.

Best regards,

Hi Vince,

Thanks for your patience. The schematic looks good to me generally.

It is recommended to have a higher VC capacitance: >= 22 uF and 1210 or larger size.

Besides, TIDA-00617 (https://www.ti.com/tool/TIDA-00617) is a TPS23751 based 5-V 5-A reference design which you can refer.

Please let me know if you have further questions or concerns.

Best regards,

Diang
