About ADP1613 COMP pin absolute maximum rating


I have a question about COMP pin absolute maximum rating.

In the datasheet, COMP to GND = 1.0V to 1.6V.

But I don't know 1V to 1.6V absolute maximum rating. 

Is the operation range 1V to 1.6V?

My customer found 2.1V COMP pin voltage in the customer board at start-up.

So I would like to confirm about the absolute maximum rating of COMP pin.

Best Regards,

    Than you for your reply.

    Yes, COMP pin connected to RC network only in the customer schematic.

    But COMP pin voltage go to 2.1V at start-up. Please see the following waveform.


    I would like to confirm about the COMP Clamp High Voltage function.

    Because ADP1621 have this function.(Vcomp.clamp=2Vtyp)

    Do ADP1613 likely to have this founction?
