Hi,

Does TI have NCP81109F alternative part?

I'm checking with customer platform information.

Thanks!

The TPS544C26 may be the closest https://www.ti.com/product/TPS544C26

The cross reference https://www.ti.com/cross-reference-search/singlepart?searchTerm=NCP81109F does not yield anything

The parameter search shows the following devices

Hi David,

TPS544C26 datasheet shows support VR13 SVID interface. Is it also can support VR12 SVID?

Or we have other buck controller can support VR12 Intel Broadwell platform?

Thanks!

The TPS53622 was the recommendation at the time of the post. A product line other than mine has a more broad selection of SVID device, the TPS53622 is supported by this group.

Hi Daivd,

As the mentioned, "Intel does not support an integrated multi-rail PMIC for the Broadwell DE line, only for the Broadwell mobile SKUs."

Seems TI have no PMIC solution can't support Broadwell platform, right?

Thanks!
