LMZ14202H: a harbinger of trouble

Hi there.

In general, what are some pre-existing symptoms before the end of the converter's life?

For example, is a constant drop in output also considered the common foreshadowing?

Thank you

Hello,

A constant drop in the output voltage could be due to the converter operating in Dropout condition or near current limit and not necessarily a sign of the end of the converter's life.

Could you provide more information regarding the operating conditions that you are expecting?

Hi Harrison.

Thank you for your response.

As a result of checking, it was confirmed that there was a problem with the external device, not the IC alone. The problem has been solved.

Thank you.

Regards.

NS You.
