I have a simply dc-dc converter (TPS5450) in adjustable mode using a simply 10K linear potentiometer. The problem is the non-linear output of feedback of the step-down. When I try to regulate output voltage in first rotation of potentiometer the sensibility is good but in the last part of the rotation it becomes much more sensitive. For example : in the first 45 degrees of rotation of potentiometer I have a change of 1-1.5Vdc in the output voltage, but in the last 45 degree of rotation I have a change of 5-6Vdc. I have read that it is a common problem in simply configuration of DC-DC converter without specific circuit for the feedback line. I need to solve this problem with specific circuit with this function.

Dear Client, I've read your task description with much interest, and i can confidently say that the a great fit for this job. As I'm a power electronics engineer with significant experience in the automotive sector. After seeing your schematic and checking the controller's datasheet, it is quite clear why you are facing such behavior. In fact, I've taken the liberty to plot your Vout voltage as a function of the potentiometer position (in nominal conditions), Please check the link below to access the graph.

The output voltages of switching regulators are basically regulated, which means that the regulators are provided with a function that maintains a set voltage at a fixed level. For the regulation, the switching regulator feeds back the output to a control circuit. Hello this is Collins and am an Engineer by profession and I can assist you in the project.
