Tool/software:
Hello,
I require your assistance in regard to the following circuit, I have seen this problem in other questions in the forum so maybe the answer is already given but I didn't search enough. I want to convert 12V to 3.3V following the details from the datasheet. I used the TINA TI to simulate the schematic and I received the desired result in the simulation. After testing the PCB i got around 0.3 to 0.6 DC at the output and the SW waveform is unstable and the coil is producing noise. Should I change something in the diagram 1st? If needed I will send images with the layout.
