They form the classic compensation network. My original idea was to change the voltage at the sensing pin of the IC wich turns to be IN to fool the IC into changing the duty cycle and thus making the output voltage higher or lower. My board has 3 transformers main, secondary. Extra rules apply to questions on vehicle electronics – please read before posting.

I believe if I can adjust the voltage on the IN pin with a variable resistance I can trigger the IC into thinking there was some voltage drop or up in the output and therefore, the IC would try to compensate this voltage by adjusting the duty cycle, thus making the output voltage up or down.

That is not something that will happen when changing R57 or VR2. I tried on both reference pins 12 and Built-in high precision oscillator provides accurate protection and delay time for monitoring. Sample Order Paid samples.
