Tool/software:
I am using a TPS54J061RPGR DC/DC converter.
Currently, to adjust the output voltage I have connected a fixed resistor to FB-GND and a digital potentiometer to FB-SW.
If I were to achieve this using a DAC, I thought I would be able to find the desired output voltage by connecting the DAC output to the FB terminal (is a current limiting resistor necessary?) but am I wrong?
I think I would get the same performance if I input the DAC output voltage to the FB input using a resistive voltage divider.
