TPSM846C23: Alternate part suggestion

Part Number: TPSM846C23
Other Parts Discussed in Thread: TPS546E25, TPS544C27, TPS546C25, TPS544E27

Tool/software:

Hi,

Currently we are using TPSM846C23 part for our design. Input-5V, Output voltage-0.68V and 0.75V & Load current-70A. Requesting you to choose the alternate part for the mentioned part number with min 5- 10mV step increments (VID change), since this part is going to be used for core rails.

Also need the features with either PMBus OR I2C

Regards,

Nandhini A.

    Hi Nandhini,

    You can still use TPSM846C23 x2 if you translate linear to VID. If that is not an option for you, then you may look into incoming devices like TPS544C27/TPS544E27 (max IOUT=35A/40A), it offers PMBus and SVID capability however I don't believe it's stackable or TPS546E25/TPS546C25(max IOUT=50A/35A) which is stackable but doesn't have directly VID.

    Regards,

    Eileen
