LM Buck Converter equivalents, price and datasheet
Your name or email address: I used the following equation as per the datasheet: It was the diode around the wrong way. Thanks for your help tho. Discussion in ‘ Power Electronics ‘ started by tshaApr 26, Table 3, page 15, shows a table for selecting the output capacitor, and pages following that discuss the input capacitor. Apr 26, 5 0. That might explain why I didn’t have CB.
Apr 26, 4. Wish I could delete this thread, failed project, failed post haha. I’ll go back see if I can find the right size. Do you already have an account? I am learning and hopefully, one day soon can help others.
Cb is shown in the data sheet as 0. Voltage regulator and caps getting very hot Posted by andrei. Okay so I change the input capacitor to uF electrolytic and the output to 47uF.
This is the data sheet I have been using: I didn’t think it was wrong because the previous one I built had it that way and still worked. Still the IC is just getting hot and only outputting mV. The capacitor values are much bigger than those suggested for input and output by the data sheet.

12v to 6v Buck Converter LM2675-adj producing no output voltage and getting very hot
Nov 12, 3, 2, Quote of the day. The problem is I am getting only a few mV on the output and the LM gets super hot fast. Apr 26, 2. I followed the instructions in the LM datasheet.
