Audiophile SMPS

2 posts / 0 new



i am to design a SMPS for audio equipment (speaker etc.).


Actually the SMPS is intended to supply the ST STA350bw Class-D amplifier (2x50W, 5 - 26V primary and 3.3 logical voltage).


My question is which product of yours is best suited for this?

Should be "audio silent" and able to supply high peak power and has a good efficiency level.


I downloaded the PI Expert and had a first look.


There are not all chips from your webpage included that are listed for audio applications.


maybe you can suggest me an ic.



we have a few product families designed for audio applications. Please visit our website

the first few design examples address the power level you are looking for. The design examples include LLC and flyback topologies. You can check our design report to see which one is better for your system
