That might explain why I didn’t have CB.

I’ll go back see if I can find the right size. It was the diode around the wrong way. This is the data sheet I have been using: I made sure my soldering is good.

Jun 4, 6, 1, I didn’t think it was wrong because the previous one I built had it that way and still worked. Apr 26, 2. I am learning and hopefully, one day soon can help others.

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

Still the IC is just getting hot and only outputting mV. I am trying to convert from 12v to 6v. I just can’t diagnose what I am doing wrong any help would be appreciated. Wish I could delete this thread, failed project, failed post haha. Apr 26, 1. Your name or email address: I have rebuilt this circuit 5 times on different boards and different layouts.

Buck converter output voltage ripple Posted by notoriusjt2 in forum: Apr 26, 3. I just realised, I made a typo and continued it.


Apr 26, 5. I am using the following parts: Apr 26, 7. Okay so I change the input capacitor to uF electrolytic and the output to 47uF. Control an Arduino with Bluetooth This article will show you how to set up two way communication between an Arduino and your Android Smartphone using Bluetooth.

I followed the instructions in the LM datasheet. The problem is I am getting only a few mV on the output and the LM gets super hot datashret. No, create an account now. The capacitor values are much bigger than those suggested for input and output by the data sheet.
