Other Parts Discussed in Thread: TPS62273
To whom it may concern
In a design I use the LMR33620C-Q1 (2.1MHz) to generate a 5V supply from a 18 - 30V input supply
I experience the IC burns off randomly when the input supply is applied and I can't figure out what the reason are.
The maximum load on the 5V supply is 1 - 1.2A included the load on the TPS62273 3.3V supply which use the 5V supply as input supply
The application circuit is shown in the attached file.
As I am stuck in the debugging, can anyone comment what I should look for in order to check what the root cause might be?
I have seen a similar problem with a LMR36503MSC3R IC which I have entered in another thread
Looking forward to hearing some comments
