Your name or email address: The capacitor values are much bigger than those suggested for input and output by the data sheet. Posted by jrd-aac in forum: Wish I could delete this thread, failed project, failed post haha. Still the IC is just getting hot and only outputting mV.

LM Buck Converter equivalents, price and datasheet

I am using the following parts: Apr 26, 2. That might explain why I didn’t have CB. Apr 26, 7. I used the following equation as per the datasheet: Apr 26, 9. I have rebuilt this circuit dagasheet times on different boards and different layouts.

I’ll go back see if I can find the right size. You May Also Like: This is the data sheet I have been using: Yes, my password is: Okay so I change the input capacitor to uF electrolytic and the output to 47uF. Thanks for your help tho. The problem is I am getting only a few mV on the output and the LM gets super hot fast.

Cb is shown in the data sheet as 0. I am trying to convert from 12v to 6v.
