Hi team,

Do you have PSRR value from f = 10 kHz to f = 20 MHz?

Hello Shoji,

Unfortunatly, We do not have measurement data of PSRR. Switching converters in general have high PSRR.

This data is not specified in the datasheet, as it also depends upon the BOM also, like inductor and capacitor at output.

Thanks,

Hi Farheen,

Understood. But PMIC team has spec'ed (PMIC needs some ext. components, like in/out caps). What is the differences? This is because MVB didn't target noise spec required EE, such as radar application?

Hello Shoji,

I am not the right person to comment on PMIC. I will recommend you to check with the PMIC team. But It idepends upon the design, it has multiple rails integrated with the design circuitry on the single die but you need rest of the external components.

TPS628503-Q1 has been used successfully in the Radar application and in case you are not aware, we have the reference design with AWR6843/IWR6432.

Thanks,
