Hi Lei,

Can you provide your schematic for me to review? Normally when you go below the input UVLO threshold the device will stop switching and Vout will slowly discharge to 0V through the output caps. In this case it looks like something is causing the device to momentarily switch on before it completely discharges.

Regards,
Jimmy

Hi Lei,

Can I get an update on this? I'd like to take a look at your schematic to help troubleshoot the issue. What is your conditions(VIN,VOUT,IOUT)? I'd like to test this on a LMZ13610EVM for comparison.

Regards,
Jimmy

Hi Lei

I haven’t heard back from you, I’m assuming you were able to resolve your issue. If not, just post a reply below (or create a new thread if the thread has locked due to time-out)
