LM Buck Converter equivalents, price and datasheet
The capacitor values are much bigger than those suggested for input and output by the data sheet. I didn’t think it was wrong because the previous one I built had it that way and still worked. Apr 26, 2. The problem is I am getting only a few mV on the output and the LM gets super hot fast. No, create an account now. Yes, my password is: Apr 26, 1.
I used the following equation as per the datashwet Thanks for your help tho. I’ll go back see if I can find the right size. Discussion in ‘ Power Electronics ‘ started by tshaApr 26, Wish I could delete this thread, failed project, failed post haha.
I just realised, I made a typo and continued it. Cb is shown in the data sheet as 0. I followed the instructions datashet the LM datasheet. This is the data sheet I have been using: Buck Converter Output Voltage Posted by notoriusjt2 in forum: Buck converter output voltage ripple Posted by notoriusjt2 in forum: I have rebuilt this circuit 5 times on different boards and different layouts.

LM2675 – LM2675 1A Step-Down Voltage Regulator Datasheet
It was the diode around the wrong way. Apr 26, 9. I just can’t diagnose what I am doing wrong any help would be appreciated. Okay so I change the input capacitor to uF electrolytic and the output to 47uF.
Still the IC is just getting hot and only outputting mV. I am learning and hopefully, one day soon can datasbeet others. What size caps would you guys suggest?
