Nov 12, 3, 2, It was the diode around the wrong way. That might explain why I didn’t have CB. I am trying to convert from 12v to 6v. What size caps would you guys suggest?

12v to 6v Buck Converter LM2675-adj producing no output voltage and getting very hot

Quote of the day. Apr 26, 4. Still the IC is just getting hot and only outputting mV.

Apr 26, 6. Okay so I change the input capacitor to uF electrolytic and the output to 47uF. Buck converter output voltage ripple Posted by notoriusjt2 in forum: I am using the following parts: Thanks for your help tho. Apr 26, 7. Jun 4, 6, 1, The problem is I am getting only a few mV on the output and the LM gets super hot fast. Discussion in ‘ Power Electronics ‘ started by tshaApr 26, Apr 26, 9.

LM Buck Converter equivalents, price and datasheet

I didn’t think it was wrong because the previous one I built had it that way and still worked. Wish I could delete this thread, failed project, failed post haha. Your name or email address: I dqtasheet the following equation as per the datasheet: The capacitor values are much bigger than those suggested for input and output by the data sheet. I made sure my soldering is good.

LM2675-5.0 Buck Converter overview

I’ll go back see if I can find the right size. I have rebuilt this circuit 5 times on different boards and different layouts.

I followed the instructions in the LM datasheet. I just can’t diagnose what I am doing wrong any help would be appreciated. Apr 26, 3.
