TPS546D24AEVM: single phase operation setting

Hey there,

My customer has this 2phase EVM in hand. What it the simplest way to make it single phase? Then, they will evaluate it with Fusion.

Thanks.

    Hi,

       Here are the instructions to convert 2-phase to single phase on TPS546D24A EVM.

    1)      You need to depopulate the 0-ohm resistor between the Master and Slave devices VSHARE pins

    1. a.       R15_P1 or R15_P2

    2)      You need to populate a 0-ohm resistor between the Master device’s MSEL2 pin and AGND

    1. a.       R18_P1

     

    At that point, the Master device will boot up in single-phase mode and will not attempt to communicate with the slave

    The Slave device will boot up and wait for instructions from the Master via BCX.  It will hold its VSHARE pin low, but with R15_P1 or R15_P2 removed, that will not affect the master device.

    Regards,
    Gerold
