Hello,
I'm working with the LMZ34002 and was looking at page 2 of the datasheet that list ABS MAX rating for the various pins. UNH/UVLO is limited to no more than 5V above A_VOUT.
Moving to page 22 of the datasheet, I see that we are showing plots of the INH/UVLO pin in reference to the A_VOUT. The measured delta here is 17.5V.
II suspect that VINH is the voltage at the gate of the "INH Control" FET. Is that correct?
