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.

Apr 26, 9. Nov 12, 3, 2, Voltage regulator and caps getting very hot L2m675 by andrei. Do you already have an account? I used the following equation as per the datasheet: Table 3, page 15, shows a table for selecting the output capacitor, and pages following that discuss the input capacitor.

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.

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.
