The VOUT_MAX command sets an upper limit on the output voltage the unit and can command regardless of any other commands or combinations. The intent of this command is to provide a safeguard against a user accidentally setting the output voltage to a possibly destructive level.

| 15:0 | VOUT_ MAX | RW | NVM | Maximum output voltage. ULINEAR16 absolute per the setting of VOUT_ MODE. Refer to the following description for data validity. |
While conversion is enabled, any output voltage change (including VOUT_COMMAND, VOUT_TRIM, margin operations) that causes the new target voltage to be greater than the current value of VOUT_MAX will cause the VOUT_MAX_MIN_WARNING fault condition. This result causes the TPS546D24S to:
Although the scenario is uncommon, note that the same response results if the user attempted to program VOUT_MAX less than the current output voltage target.
