Part Number: CC2640R2F

what is the CC2640R2F global ldo power consumption?

what is the CC2640R2F DC/DC Converter Mode power consumption?

Is there any data comparing the power consumption of "global ldo mode" and "DC/DC Converter Mode"

Hi Hank,

You can look at the current vs. supply voltage plots in section 5.29 of the datasheet. The flat section to the left is where the DCDC is disabled and the LDO is used instead. If you do not use the DCDC at all, the current consumption will be similar to the flat section for all voltages.

Regards,
Fredrik

It is approximately the same as for LDO mode.
