Part Number: TPS54202

Tool/software:

To whomsoever it may concern,

With regard to the above mentioned part number (TPS54202), I am seeing a beep(short) on the DMM when i probe at the SW node pin of the IC. Is this a sign that my IC has gone bad or is it something else?.

Hi Shreyas,

Can you please share more details? Short: SW pin wrt GND? Is the buck functional or is yielding no output?

Regards,

Gautam

Shreyas, just a quick check. I guess, replacing the chip would've resolved your issue?

Hi Gautam,

I have not replaced the IC yet, though on removing it all the short conditions disappeared. Which makes me guess that it is an IC issue and that on populating a new one, the board will function as normal.

Agree. I'll close this thread in that case.
