TDA7269A Power Supply

 TDA7269A Power

 

Because the TDA7269A's operational voltage range is 5 to 20 volts, we'll need an 18-0-18/ 2amp 18 volt AC transformer, as well as a bridge rectifier IC and a filter section.

The TDA7269A based amplifier power supply portion requires 20v at the power supply output.
