Hello,
We want to design with the DA14580 but power consumption is not a significant factor. Cost is. Is it possible to eliminate the external inductor (2.2uH) and bypass the DC/DC if we can ensure that 3.3V will arrive at the device? What will the connections look like?
Thank you.

I am also interested in this. Could you please send this information to my email?
Thank you
looks interesting to me too :)

This would be helpful. Please send my way too. Thanks much.
Hi all,
It is possible to directly connect the supply voltage and bypass the DCDC (and not mount the inductor). We have been in the process of qualifying the DA14580 to work on an input voltage up to 3.3V. (with the internal DCDC, the internal voltage is 1.4V), and we can confirm now that this is supported. We however still need to define the exact operating conditions in the next release of the data sheet. Therefore this is still preliminary.
Best regards, RvA
I'm very happy to find this info.
Please email me too.
Thanks.
这个有消息了吗?
I'd appreciate an update on this as well. If I'm reading your reply right we can supply 3.3v regulated power and NOT use the external 2.2uh inductor? Or must we supply 1.4v regulated power in order to not use the inductor? Our design has a 3.3v regulator on it since we are running from a single cell lipo battery.
