I want to be able to control the voltage output of a Buck regulator with an MCU
I read that I can use a DAC output to adjust the voltage going through the Feedback pin of the regulator but I'm a little lost as to how to go about this
The Buck will have a voltage input of around 5.2V
Can you help me understand how to accomplish this? Do I need some sort of filtering on the DAC? Is an 8-bit resolution DAC enough to do this?
I want to use these parts:
AP3429KTTR-G1
ATTINY817-MFR
Thank you in advance!
