TPS63060: Power supply rejection specification

Hi John,

If I understood correctly, you are interested in output voltage ripple, and PSRR performance of the TPS63060. Could you please give us the specific operating conditions (Vin, Vout, Iout), and we will look into the data?

Best regards,
Milos

Hi Milos,

Yes, please let me know the performance of TPS63060 in terms of output voltage ripple and PSRR. Here are my operation conditions.

Vin = 2.7 to 4.2 V (Source: Lithium-Ion battery)

Vout = 2.83 V

Iout (max) = 0.5 A. 

Here is my schematics.

Regards,

John

Hi John,

Sorry for the delay. Due to the outbreak and limited lab access, it will take us some time to do the measurements. We will let you know the timeline early next week.

In the meantime, could you please tell us why did you choose the TPS63060? This device is suitable for higher input/output voltages. For the above conditions (Li-ion input, Vout = 2.8 V), we would recommend another device, for example the TPS63030,

Best regards,
Milos

Hi Milos,

Thanks for your suggestion. I chose this part as a common design for existing products. If TPS63030 can provide better noise performance, I will consider changing it. If you can provide some performance data for TPS63030 using our requirements, that would be nice as well. Thanks.

Regards,

John

Hi John,

We'll do our best to get your measurements by the end of the week.

Hi Milos,

Thank you so much for your support. That's really helpful.
