What size caps would you guys suggest? Thanks for your help llm2675. Yes, my password is: Okay so I change the input capacitor to uF electrolytic and the output to 47uF. The problem is I am getting only a few mV on the output and the LM gets super hot fast. Apr 26, 4. Your name or email address: I am trying to convert from 12v to 6v.

Table 3, page 15, shows a table for selecting the output capacitor, and pages following that discuss the input capacitor.

I made sure my soldering is good. I used the following equation as per the datasheet: Apr 26, 1. Nov 12, 3, 2, Posted by jrd-aac in forum: Do you already have an account? I’ll go back see if I can find the right size.

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

Buck Converter Output Voltage Posted by notoriusjt2 in forum: Apr 26, 3. I have rebuilt datashheet circuit 5 times on different boards and different layouts. Apr 26, 7.

Apr 26, 5. That might explain why I didn’t have CB. I didn’t think it was wrong because the previous one I built had it that way and still worked. This is the data sheet I have been using: Apr 26, 2.
