Is there a SPICE model for the DCDC convertors in the NRF52 ?https://devzone.nordicsemi.com/f/nordic-q-a/78685/is-there-a-spice-model-for-the-dcdc-convertors-in-the-nrf52We are using the NRF52 as a SoC in a sensitive analog application, I need to model power supply noise created by the DCDC convertors REG0 and REG1. Is there a SPICE model for these convertors?en-USTelligent Community 13Thu, 19 Aug 2021 08:40:44 GMTRE: Is there a SPICE model for the DCDC convertors in the NRF52 ?https://devzone.nordicsemi.com/thread/325656?ContentTypeID=1Thu, 19 Aug 2021 08:40:44 GMT137ad170-7792-4731-bb38-c0d22fbe4515:354642eb-22fa-4e28-8689-eeceac5a519fketiljo<p>I&#39;m sorry, but that&#39;s not available. The regulators works in several different modes depending on the current requirement so a SPICE model will quickly become very complicated. The main problem will be the relative high current draw when the radio is operating. Consider&nbsp; a separate regulator for the nRF52, separate power tracks etc. to isolate the power supply noise that the nRF52 generates. The DCDC converters doesn&#39;t contribute much to this.</p><div style="clear:both;"></div>
