I need to design 400W AC to DC Isolated Power supply for Class D Audio Power Amplifier. The TAS5630B class D TI chip is using. Is it advice able to use switching power supply for Audio amplifier application. It will affect the audio output performance due to harmonics? or we shall go with stepdown transformer power supply.
Kindly share the 400W Power Supply reference design for below mentioned voltage range.
Vin - 85 to 250V 50/60Hz
Vout - 35V DC
Iout - 12A
