I am learning and hopefully, one day soon can help others. The problem is I am getting only a few mV on the output and the LM gets super hot fatasheet. Apr 26, 3. Apr 26, 8. Your name or email address: Wish I could delete this thread, failed project, failed post haha. I have rebuilt this circuit 5 times on different boards and different layouts. Voltage regulator and caps getting very hot Posted by andrei. I just realised, I made a typo and continued it. Apr 26, 6. Apr 26, 1. It was the diode around the wrong way.
Quote of the day. Jun 4, 6, 1, What size caps would you guys suggest? Apr 26, 7. LM Buck Converter equivalents, price and datasheet 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. Apr 26, 4. Thanks for your help tho. Apr 26, 5. I used the following equation as per the datasheet: No, create an account now. Still the IC is just getting hot and only outputting mV.
Okay so I change the input capacitor to uF electrolytic and the output to 47uF. Cb is shown in the data sheet as 0. The capacitor values are much bigger than those suggested for input and output by the data sheet. I am using the following parts: Apr 26, 2. I am trying to convert from 12v to 6v.
