Hi Scott,

Yes, that's all the available data.

I saw that info in the datasheet. If that's all that's available, we will do what we can.

Thanks,
Scott

Hi Scott,

No, we currently do not have such curves in the PS.

What we have is detailed current consumption numbers for a variety of operating modes and also for each of the peripherals. These current consumption numbers are measured with the DC/DCs operating so the loss of the DC/DC converters is already included.

For some parameters we also have plots of current consumption vs supply voltage, such as here for the radio:

I think what you need is all there already.

Hi Scott,

I am checking with the internal and will back if I have anything to share.
