i like sharing, but it is not as easy as seems. there are millions of PDF files out there. you must find them all to make useful website. and i surely did it. try now to find and download any PDF file you ever knew and you can find that file on my website.

In reply to Samuel Jaffe: My design requirement is input voltage 10 to 30 V and output current of 2. Because I have replaced it with Tantalum, but the regulator fails to work properly, the output is not stable. TI is a global semiconductor design and manufacturing company. Aug 19, 3: Currently for a project I have choose TPS and have designed a board with it. Ask a new question Ask a new question Cancel.
No license, either express or implied, by estoppel or otherwise, tps540 granted by TI. But for my design it costs pretty high. Menu Search through millions of questions and answers User.
I have removed the compensation network and replaced ceramic capacitors with tantalum.

Do you have excessive ripple on VOUT? In reply to Tps4530 Jaffe:. The output is fed to a processor, so if the processor is loaded to its maximum, it draws a variable current from 2A to 2. Go to Support forums.
Aug 20, 2: Thanks for your feedback, it worked: We can also try to see if there is an issue we’re not considering. Please find my schematics as attached.
Ceramic tp5s430 can also produce audible noise. But I’m not sure whether it will cause any problems. Use of the information on this site may require a license from a third party, or a license from TI. If so, that may cause more audible noise and should be fixed before we change the power stage. We are glad that we were able to resolve this issue, and will now proceed to close this thread.

As in the datasheet it says that tantalum and electrolytic cap will have high ESR value,it will be better to use ceramic. I suspect that this buzzing noise humming noise is from the inductor. Sathiya, First make sure it’s the inductor and not the output caps.
Sep 4, 9: Try the tantalum or aluminum caps on the output again but remove the compensation C54, C55, C Mentions Tags More Cancel. If you have a related question, please click the ” Ask a related question ” button in the top right corner. This may help stability since the IC has compensation built-in for this case. In reply to sathiya narayanan L: Do you have another question?
If it is the inductor you can try using a fully-shielded inductor, try an inductor with larger pads for more solder connection, or ask your inductor vendor for their recommendation on low audible noise inductors.
Sathiya, Yes, ceramic will have lower ESR but if they are causing the issue then you will need an alternative. Aug 27, 7: Ask a related question What is a related question? If you have further questions related to this thread, you may click “Ask a related fps5430 below.
