Hi Team,
When using the current TPS54260, customer found that there is a big difference in the input-output drop difference in the normal working state (PWRGD is not low).
The same PCB, early TPS54260 material input 5.4V, output 5V state, still can guarantee 5V output, PWRGD is not low
An example of an existing TPS54260 material is to input 6V and output 5V to ensure 5V output, and PWRGD is not low. When the input is lower than 6V, PWRGD will output low level.
In another example, the limit is 5.8V.
So when output is 5V, how big does the input need to be to guarantee the output?
