This One Line of Code Could Halve Your Power Consumption on D52 and N5 Modules
Did you know that Dynastream D52 and N5 modules natively support the onboard switched DC-DC converter with no additional external components required? Did you also know that the example code which comes with the SDK does not enable the onboard DD/DC converter by default in order to be out-of-the-box compatible with devices which only support the LDO, and it's a place where most developers tend to start? By enabling the DC/DC converter, the chipset is able to take advantage of the efficiency provided by the switching converter when the active current is high and the idle current of the converter is negligible in comparison.
Thus, if you are using a Dynastream module and you are starting your work from an example, remember to add this line to your code after you setup the SoftDevice and see your power consumption drop!
