NRF5340dk - nPM1300 Buck Regulators

[erifat]

Hello I have a few questions

In my project, the nPM1300 fuel gauge example via nrf5340dk works properly. I received information such as V - I - SOC via I2C. Currently I want to control the 1.8V output via V1 and V2 buck converter. There is no structure in the sample code where I can access the registers. How can I control Vout outputs via software? Is there an example application? I want to be able to turn on and off the 1.8 V outputs of the nPM1300 via software.

thanks

Hi.

You can use regulator_enable/disable to control the bucks and ldos.
The npm1300_one_button sample uses this to control LDO1.

e.g.:

static const struct device *buck1 = DEVICE_DT_GET(DT_NODELABEL(npm1300_ek_buck1));
...
regulator_enable(buck1);
regulator_disable(buck1);
