    Hi,

    I do not think the initial output voltage could be modified prior to shipment.

    Customer can change the initial boot voltage using PMBUS command MFR_SPECIFIC_11 (address DBh). You can refer to the Technical Reference Manual of TPS53681, which is the multiphase controller used internally by TPSM831D31, for more information.

    Technical Reference Manual for TPS53681 is available on TI.com, under technical documentation section:
