I want to use a buck converter which steps down 12 V DC to 5V5 V constant DV output to power my custom PCB.
I came across a buck convertorconverter in market which can do it but there is potentiometer on it which can be adjusted to vary the output voltage.
Below you can see the schematic for the buck convertorconverter and where I plan to remove the potentiometer and put fixed resistors to get a 5V5 V constant output.
Can someone help me in how to put fixed resistors in place of potentiometer and how to calculate the value of resistor?
