TPS53511 TPS24751 Schematic Review - Debug Hot Insertion using TI DC/DC Power devices

Other Parts Discussed in Thread: TPS53511, TPS24751

Hello Team,

My customer needs some help with with a debug effort with the TPS53511 and TPS24751

 where it doesn’t start up or might shut down on hot insertion into their system. 

Note so far there is one card where the supply doesn’t start up.  The issue is working it's way through debut but any feedback would be much appreciated.  Note it is observed where Vfb gets noisy.  The customer would like feedback if this could be a contributor to the start up issue.
