TPS2373-4EVM-758: TPS2373-4 design for IEEE802.3bt PD

Dear Sir

1. We plan to design a PD splitter product. but two solution (TPS2372-4 and TPS2373-4)

Which one is more  suitable solution.

Our require input power only form PSE, Output can great than 71.3W (PD standard) in short cable, such as 5m cat.5e cable

We have some confuse on power delieve to PD on short cable

Because two chip of spec mention “802.3bt (Type 4) , PD INPUT POWER (MAX) is 71.4W on the list table . TPS2373-4 and TPS2373-3 to support high power applications up to 90 W on the Description ..Could you please help to clarify?

2. Can we implement output voltage to support 12V/19V/24V by using DIP Switch to change UCC2897A output .it is have any extra reference design we can obtain ?

Thanks
