Hi Roy,

Thank you for reaching out to us.

For the above requirements, I would suggest one of our latest devices, TPS6284x, a high-efficiency converter with ultra-low operating Iq of typically 60 nA.

Please have a look at the datasheet:

If there are some other features that you are specifically looking for, we can discuss further internally and I can propose an appropriate solution.

Regards,

Febin

Hi Febin,

Tiny package is must spec because application is smart watch. Do we have DSBGA package solution and having lower Iq?

Hi Roy,

I would recommend our TPS6284x high-efficiency step-down converter with ultra-low operating quiescent current. It also comes in a WCSP package.

Please have a look at the datasheet: https://www.ti.com/lit/ds/symlink/tps62840.pdf?ts=1591253780478
