TPA3116D2: Audio Boost, Buck Transformer specification

Part Number: TPA3116D2

Is the output of TPA3116D2 suitable to be boosted to 70v with booster transformer?

I thought of using it for multi room audio where every room has a 70v - 2v step down transformer that feeds a TPA3116D2.

Customized volume for each room is the idea. 

Need help for the following:

1. What is the peak speaker output voltage if 24v DC is the input voltage?

2. Audio booster (speaker output voltage to 70v) & audio buck (70v to 2v) transformer specification for TPA3116D2.

  • 1. If the Plimit is set to maximum, the peak voltage is 24Vdc.
    2. Transformer loads need special care and is discussed in this Application note: www.ti.com/.../sloa133.pdf
