HiperPFS-3 and HiperLCS for ±28V

Posted by: djsfathomtree on

Hi,
I've been looking at the HiperPFS-3 and HiperLCS for an audio amplifer supply ±26 V.

See block diagram here.

I am looking for the following qualities.

- sum of voltages across the ±28 V outputs well regulated
- excellent voltage regulation / transient response  (no-load to full load)

Is my idea suitable for audio applications?

Thanks.

your system looks OK. the comments is the PFS stage will see >400W from the LCS outputs you gave. Noted the PFS7529 can works with rated power of 405W as recommendation.

the LCS -Ve need some design to work with negative output.
