Part Number: TPS546D24

I have the TPS546D24 part on my PCB - that i am trying to gring -up and have hit a wall on this part.

My parameters are ;

Vout = 0.8V

I out = 26A

Freq = 550KHz

V resolution = 0.74V to 0.89V with 0.01 step

I need the strapping resistor value to implement this on VSEL, MSEL1, MSEL2 & ADRSEL pins.

  • Hi, I will get somebody back here to support you. Sorry for the late response.

    The TPS546D24 has a wide range of design and support tools available in the TI MySecure Software folder for the device.  You will need to go to the TPS546D24 product folder and select the "Request Now" link to request access to the secure folder.

    There you will find design tools for the TPS546D24 including:

    Full Datasheet

    Supplimental User information, including the warning that the Pin Programming Function is not designed for operational life and initial PMBus values must be stored to NVM and Pin Detection disabled as part of production flow to ensure reliable operation over the product life.

    Power Stage and Compensation Excel Design Tool

    Pin Programming Design Excel Tool

    Schematic and Layout review check lists

    FUSION Digital Designer project files

    For new designs, I would recommend considering the TPS546D24A, which is a pin to pin compatible device to the TPS546D24 that offers the same Power Stage, Control, and PMBus features, but uses different Pin Programming resistors in order to provide Pin Programming that is rated for full operational temperature and product life.
