TPA3220: Minimum capacitance of PVDD decoupling

Part Number: TPA3220


Dear Specialists,

My customer is considering TPA3220 and has a question about decoupling capacitance of PVDD.

I would be grateful if you could advise.

According to the datasheet P31. 10.2.1.2.1 Decoupling Capacitor Recommendations,

it is recommended  1uF, X7R and 50V( at 30V power supply)

Since the delivery of the ceramic capacitor is bad, it is difficult to obtain X7R, 50V rated products.

So please tell me the minimum capacitance of decoupling capacitor regarding PVDD.

With that information, I can check capacitor series (X6R, X5R etc) and other types (dielectric).

If you have any recommendation of alternative capacitance information, could you please provide.

I appreciate your great help in advance.

Best regards,

Shinichi
