Class D Multiphase explanation

[rtarbell]

Can someone explain/give reference to what multiphase class-D is and how it works?

Thank you!

As a rough explanation, splitting the work load across multiple output stages, having them sum at the output.

Look up the patent # Bruno provided.

Are you sure all class d amps have 0 PSRR?

I thought they did, but I could be wrong...
My info is coming from an IRF tutorial document:
