Wish I could delete this thread, failed project, failed post haha. I just can’t diagnose what I am doing wrong any help fatasheet be appreciated. Thanks for your help tho.


I used the following equation as per the datasheet: The capacitor values are much bigger than those suggested for input and output by km2675 data sheet. I just realised, I made a typo and continued it. No, create an account now. Apr 26, 2.
