The DC/DC converter is not enabeled by default. Set it by using the function sd_power_dcdc_mode_set(). This will dynamically turn on and off the DCDC depending on current draw scenarios.

DC/DC is only efficient when a large enough amount of current is drawn, therefore the chip switches between the most efficient solution, ie. LDO or DC/DC.

Do I need to explicitly enable the DCDC converter or is automatically enabled when I initialize the soft device. Is the call to "sd_app_evt_wait()" sufficient to disable the DCDC converter based on the fact that the errata no longer applies?

Thanks,

Rudy

Hi,

Item 1 should be engineering C, item 2 should be revision 1. This means that you should not have to apply the errata 63 for DCDC. You can refer to the compatibility matrix to decode chip revisions.

Best regards,
