PRODUCTION DATA.
The VOUT_ MIN command sets a lower bound on the output voltage to which the unit can be commanded, 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 rather than to be the primary output under voltage protection. VOUT_MIN is a VID format command, and must be accessed through Read Word/Write Word transactions. VOUT_MIN is a paged register. In order to access VOUT_MIN for channel A, PAGE must be set to 00h. In order to access the VOUT_MIN register for channel B, PAGE must be set to 01h. For simultaneous access of channels A and B, the PAGE command must be set to FFh.
If an attempt is made to program the output voltage lower than the limit set by this command, the device will respond as follows:
| 15 | 14 | 13 | 12 | 11 | 10 | 9 | 8 |
| R | R | R | R | R | R | R | R |
| 0 | 0 | 0 | 0 | 0 | 0 | 0 | 0 |
| 7 | 6 | 5 | 4 | 3 | 2 | 1 | 0 |
