When it comes to the UVLO or more of voltage,

"SS-TR" is once 0V. Then, to start after a delay time.

Customer questions.

1.LMZ30602 at the time of start-up,
to ON internal FET?
2. Until the restart, LMZ30602 have a delay time?

From your waveforms, it looks like a voltage is driving the SS/TR pin. It looks like it is a voltage divider from the input voltage. Are you trying to track another voltage at start-up?

Do you have schematic that you can share? You can send it directly to me at jarrigo@ti.com.

Thanks, Jason
