I am learning and hopefully, one day soon can help others. What size caps would you guys suggest?

LM Buck Converter equivalents, price and datasheet

Posted by jrd-aac in forum: Discussion dataaheet ‘ Power Electronics ‘ started by tshaApr 26, Quote of the day. Wish I could delete this thread, failed project, failed post haha. Yes, my password is: Thanks for your help tho. Apr 26, 6. Buck Converter Output Voltage Posted by notoriusjt2 in forum: I have rebuilt this circuit 5 times on different boards and different layouts. Still the IC is just getting hot and only outputting mV.


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

I followed the dagasheet in the LM datasheet. Apr 26, 5. You May Also Like: Do you already have an account? Apr 26, 7. I made sure my soldering is good. It was the diode around the wrong way. The problem is I am getting only a few mV on the output and the LM gets super hot fast.

This is the data sheet I have been using: Table 3, page 15, shows a table for selecting the output capacitor, and pages following that discuss the input capacitor. 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 just realised, I made a typo and continued it. Jun 4, 6, 1, The capacitor values are much bigger than those suggested for input and output by the data sheet.

Nov 12, 3, 2, I used the following equation as per the datasheet: Okay so I change the input capacitor to uF electrolytic and the output to 47uF.

I am trying to convert from 12v to 6v. Voltage regulator and caps getting very hot Posted by andrei. I’ll go back see if I can find the right size. Apr 26, 8. Apr 26, 9.

Apr 26, 2. Apr 26, 4. Apr 26, 3.

I just can’t diagnose what I am doing wrong any help would be appreciated. I didn’t think it was wrong because the previous one I built had it that way and still worked.
