Hello Kashif,

The PMP10215 doesn't have a high enough supply voltage to provide the specifications you want. If you look at the Output Power vs Supply Voltage figures in the TPA3255 datasheet it will give you a better idea of what would be a suitable PVDD to meet your specification.

Best Regards,

Luis

Dear Luis thanks

Thanks for your valuable feedback.

Can you suggest any active power reference design available on TI which I can follow and develop a power supply unit that could meet my requirement.

Regards

Kashif

Hello Kashif

https://e2e.ti.com/support/power-management/ would be a better resource to ask about power supply design. Provide information like your max current draw and the Vout should be the PVDD that fits your spec.

Best Regards,

Luis
