Hi,
I have a chain of TPS54550 voltage regulators. If there is a short at the input of TPS54550 IC, what will happen? I wonder, the short at the input of this voltage regulator will crash everything on the chain of voltage regulators and cause total power loss on PCB or is there anything to protect from this? If the problem occurs time to time with different frequency what kind of noise can be expected? Our circuit works couple of days without a problem, but time to time we are experiencing intermittent shorts at the input of the voltage regulator which is supported with a chain of same kind of voltage regulator. I am trying to figure out the effect on the entire board. Thanks and best regards,
