Hi,
the following are the TX's current consumption for 0 dBm from the datasheet:
I assume the second line refers to the measurements when the internal LDO is used and where VDD is supplied at 3V. Can someone confirm please?
Background: I am searching for the best power configuration when the device is to be powered from a Li-Ion battery and battery lifetime is a very critical aspect. If an external DCDC "switcher" is used to get from the battery to the 3V for VDD, and the nRF52840 is configured to use an LDO, will I still get measurement figures like given in the second line?
Also, can somebody explain more about the difference between ITX,0dBm,DCDC and I0dBm(DCDC, 3V)?
Thanks.
