TPS2373: Accurate current control in PMP20878

Part Number:TPS2373

Hi,

My customer needs to know for  PMP20878 how the feed-forward regulation can be tuned optimally in order to ensure that 1.0A is both requested and approved by PSE, but not surpassed at the PSE side.

The customer does not want to having to set 0.8A request just to make sure that 1.0A is not surpassed at the PSE. 

In short; how should he calculate/design for the current margins in the PMP20878 to stay as close as possible to 1.0A but not violate that limit?

Thanks for your help.  M.A.M
