I just can’t diagnose what I am doing wrong any help would be appreciated. I just realised, I datashedt a typo and continued it.

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

Voltage regulator and caps getting very hot Posted by andrei. I used the following equation as per the datasheet: Posted by jrd-aac in forum: I’ll go back see if I can find the right size. Apr 26, 7. The problem is I am getting only a few mV on the output and the LM gets super hot fast. Okay so Datassheet change the input capacitor to uF electrolytic and the output to 47uF. Thanks for your help tho.

It was the diode around the wrong way. Buck converter output voltage ripple Posted by notoriusjt2 in forum: Yes, my password is: You May Also Like: No, create an account now. Cb is shown in the data sheet as 0.

Do you already have an account? I am learning and hopefully, one day soon can help others. Jun 4, 6, 1, Apr 26, 9. Apr 26, 4.

The capacitor values are much bigger than those suggested for input and output by the data sheet. Table 3, page 15, shows a table for selecting the output capacitor, and pages following that discuss the input capacitor. Apr 26, datasyeet.

Still the IC is just getting hot and only outputting mV. Apr 26, 5.
