Team,
Regarding FMECA analysis in power supply:
Looking at the TPS54340B diagram if there is a failure with one of the feedback resistors connected to FB then the Output VOUT reaches the Input level VIN:
What do we advise in general to prevent VOUT to reach VIN in this case?
Are there some simple changes to implement in the basic application circuit that could prevent it?
Thanks in advance!
