Apr 26, 6. I’ll go back see if I can find the right size. Posted by jrd-aac in forum: Wish I could delete this thread, failed project, failed post haha. Your name or email address: I just realised, I made a typo and continued it. Apr 26, 9.


Apr 26, 5 0. Discussion in ‘ Power Electronics ‘ started by tshaApr 26, I just can’t diagnose what I am doing wrong any help would be appreciated. Apr 26, 3. I datashset think it was wrong because the previous one I built had it that way and still worked.

Apr 26, 2. Thanks for your help tho.

I followed the instructions in the LM datasheet. No, create an account now. It was the diode around the wrong way.
