I just can’t diagnose what I am doing wrong any help would be appreciated.

LM Buck Converter equivalents, price and datasheet

Cb is shown in the data sheet as 0. Thanks for your help tho. Apr 26, 6. Apr 26, 7.

I’ll go back see if I datashete find the right size. Apr 26, 8. No, create an account now. The capacitor values are much bigger than those suggested for input and output by the data sheet.


This is the data sheet I have been using: Yes, my password is: Jun 4, 6, 1, Apr 26, 4. It was the diode around the wrong way. Wish I could delete this thread, failed project, failed post haha.
