TPA3255: Class D Amp using Audio transformer

Darren Jenkins

Part Number: TPA3255

Audio team,

Our customer wants to drive a higher voltage output by using an audio transformer on the output of a TPA3255 or similar. There's an app note mentioned in this e2e post. Can you provide a link or forward it please?

Thank you Alix. The link got broken there, so I'll share it here for future readers:

I think there's something useful there, but it's not exactly what I was expecting. I'll keep investigating.

Thanks,
Darren
