Hi Statham,

Please reference Page 33 on the datasheet for the layout guidelines. An example of a board schematic and layout can be found on the TPS2120 EVM user guide here: https://www.ti.com/lit/ug/slvubd2a/slvubd2a.pdf

Hello Shreyas:

I mean YFP package... that page 33 is not YFP package.

Please let us know where can we get the reference?

Thanks a lot.

Hi Statham,

The guidelines from Section 12.1 are the same with the consideration that TPS2120 is YFP package.

For a schematic reference, please use the TPS2120 EVM. The user guide can be found here: https://www.ti.com/lit/ug/slvubd2a/slvubd2a.pdf

Hi Shreyas:

Thanks your feedback.

Whatever datasheet provides RUX package layout recommendations not YFP package, and EVM didn't provide any layout recommendations.

Our customer has been giving up.

Thanks a lot.

Hi Tommy,

This recommendation is common to both TPS2121 and TPS2120:

We also recommend that the CSS capacitor is positioned close to the device to avoid any parasitic effects on the rise time.

For these ball grid array packages we have the following FAQ: https://www.ti.com/support-quality/faqs/wafer-level-chip-scale-package-faqs.html

And a handling guide: https://www.ti.com/lit/ml/sszqnf6/sszqnf6.pdf

Thanks,

Shreyas
