Hi
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,
Kikuchi
Hi Kikuchi-san,
Voltage should not go above 1.6V. It is not recommend to have other part of customer's circuit connected to this pin.
The Abs Max rating is an indicator of the limits to which any pin might be forced from the outside world. It has most relevance to things like supply pins and input pins, where the customer is potentially…
Hi Fil-san
Thank you for your reply.
Yes, COMP pin don't connected to the other circuit, just RC network.
But COMP pin voltage go to 2V at start up.
I would like to confirm about the COMP Clamp High Voltage function.
ADP1621 have this function.(Vcomp,clamp=2Vtyp, 2.1Vmax)
Do ADP1613 have the COMP Clamp High Voltage function?
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.
Because ADP1621 have this function.(Vcomp.clamp=2Vtyp)
Do ADP1613 likely to have this founction?
But COMP pin voltage go to 2.1V at start-up.
Let me verify with designer.
