nRF54 VDDH Config Performance Difference?

[stevely630]

Hi for the nRF54H20 the ds says there are two options for how to supply VDDH: either VDDH=2~5.5V with config 1 or VDDH=1.8V with config 2. If my system has 3.8V from a lithium ion battery, and 3.3V, and 1.8V available, then is there any preference or performance difference or trade off I should be aware of when deciding which one to use to supply VDDH ? 

Thanks, Steve

Hi, I will ask internally. Do you plan to use any form of PMIC to regulate the charging and the voltage to the device?

Yes there will be a pmic with battery charging and voltage regulators.

Okay. The internal feedback I got was there would only be a difference if you had high temperature and was using only the LDO
