https://devzone.nordicsemi.com/f/nordic-q-a/326/nrf8001-dc-dc-converter-enabledHello, This is the first time i use NRF8001 chip, i was reading the ic manual nrf8001_PS_v1.1.pdf (see attached file). It was written that in case i used DC/DC converter to step down the voltage it can reduce the power consumption up to 20%.

In the PS, this is pretty nicely described in chapter 13, so I&#39;ll recommend you to take a look on it.</p><div style="clear:both;"></div>
