Audiophile SMPS

Hi

 

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.
