Hi,
I'm currently evaluating the TPS40190. The sample schematics (slur004.pdf) contain a diode D1. On the TPS40190EVM-001 it is not populated.
When should this Diode be used? I could not find any information on this.

Hi Nico,
The diode is used to force the SW node to ground in case there is a negative overvoltage on it. This is optional and used for protection purposes.
Thanks!
