I am designing a offline power supply which will 24V as output with 2.5A. I found UC3843 as better option. I used TI we bench tool to design my power supply. This is the schematic I got from it. The given transformer design, I given to one manufacturer and I got a transformer. I rigged up the circuit as it mentioned. But in this I am getting three Issues
1) Audible noise across the transformer.
2) Sometimes(randomly) restarts while I am connecting 1A load.
3) Small ripples present in output when there is no load.
how to solve these problems
