LMZ36002: Correct use of ULVO Pin

Stoane

Part Number: LMZ36002

Hi,

I am currently developing a design with the LMZ36002 on it. We need ULVO at 6V.

There's no way to figure out how to properly use the ULVO pin as there are obviously two opposing views stated in the datasheet.

First. Did I get the following right? Pulling the ULVO pin above 2.1V to make it work and below 1.8V to make it stop?

If yes, table 10 in the datasheet is NOT consistent.

Thank you for your help!

Hi Fabian,

Yes you are correct, the UVLO pin must be 2.1V and above for the part to start working. Let me look into getting the table fixed. In your case of UVLO at 6V, you can pick the Rtop of 39.2k and Rbot of 21k to get 2.1V on INH/UVLO pin.

Jimmy
