Original question:

TPS53626: How to increase load regulation or DC gain of TPS53626

TPS53626: What is the difference between TPS53627 and TPS53626 chips?

Part Number: TPS53626
Other Parts Discussed in Thread: TPS53627, TPS53667, TPS53679, TPS53661

One of our customers chose TI power supply for the design.

Client proposal: Intel CPU is currently used for the product, and VR13.0 is required. Please refer to the TPS53627 and TPS53626 recommended by the design.

Excuse me:

A. what's the difference between these two materials?

B. We are currently using TPS53667, which is vr12.5, is it compatible with VR13.0 standard?

Looking forward to your reply!Thank you!

    Hello,

    Both devices are made for VR13.0. The difference is the DAC step size / range. 

    TPS53626: Intel VR13 5mV DAC

    TPS53627: Intel VR13 10mV DAC

    TPS53667 does not support SVID. For the core rail, our recommended VR12.5 device would be TPS53661, and our recommended V13.0 TPS53679. You can email vr [at] list [dot] ti [dot] com for more info to request a datasheet as these devices are protected by Intel CNDA.

    The Intel CPU we chose is SnowRidge.

    The CPU manual recommends TPS53626 and TPS53627. Could you recommend cost-effective power solutions, including MOS chip, and provide relevant power design materials?

    Thanks for your help!

    Hi,

    You can use CSD95372A pairing with TPS53626/27, and for reference design material you can refer to intel customer reference board schematic.

    Thanks

    Chasel.
