Hi @svarghese
Thank you so much for your interest in our products and for using our community.
Question: Do we have to use 2 different power supplies to power the VDD_SNVS_IN pin of the controller and DCDC_IN pins of the controller? We dont have a battery in the system to power VDD_SNVS_IN. Can I use same 3.3V power supply to power the controller? Do you have any application circuit for this?
Answer: I think that you don't need use 2 different power supplies to power the VDD_SNVS_IN pin of the controller and DCDC_IN pins of the controller.
If you don't need the lowest sleep power mode(SNVS mode) in your app, SNVS_IN can be POR together with other power domain to implement true one LDO or DC-DC regulator in system.
Wish it helps you.
If you still have question about it, please kindly let me know.
