Reading LDO-Output Voltage (Pin No 47 DCC Power DC/DC regulator output )

[Sherin]

Hello,

I need to read the voltage available in this Pin after the DCDC mode was enabled.

Do you have any API to read the same?

This is not possible unless you connect DEC4 to a analog input and use the ADC to read the voltage. If the internal band gap reference is used, the input must be scaled down with a voltage divider.

Thank you.. Can this API can be used to check whether DCDC is enabled or not ?

API: nrf_power_dcdcen_get()

Yes, you can read this, but not write if the softdevice is enabled. You can also read the register directly, DCDCEN

Thanks a lot ..It helped me.
