Yes

it s the 2.6k resistor that I ve measured between Vdiff and IDroop (so point 5 and 9 yes)

If I pencil this resistor, Rfb will be null right ? so Vdroop = Iavg x Rfb with Rfcb -> 0 will be null .?

Do you have an idea ?

More information for you Massman.

From my measures, I ve identified the layout scheme used with the ISL6327




As you can see, the scheme seems to be the same as datasheet one for Regulation with Loadline. The scheme have much more sense for me and for you ?

What do you think about RFB (pin 5 to 9) ? Can I use pencil to reduct its value in order to reduc VDroop ?

pin 5 to 9 was my first thought too. If it was my board, I would give it a shot, but be VERY careful!!!

Then the mod should look like this, right?

How can I be very careful ? test with a very small line of pencil, measure new resistance, test and start again with a bigger line ?

For me the VDroop mod is here :



but i m not sure :(

For the VDrop mod, i' dont know what i must do for it

On your scheme, yellow dots are already connected, I think you make a mistake in your drawing.

For the Vcore, 1 is not connected to Ground i think (I ll verify tonigh), it s connected to COMP

I forgot smthing :


THX FOR YOUR HELP

My drawing is indeed wrong, sorry, yours is good
