PRODUCTION DATA
The VOUT_DROOP command sets the rate, in mV/A (mΩ) at which the output voltage decreases (or increases) with increasing (or decreasing) output current for use with adaptive voltage positioning. This is also referred to as the DC Load Line (DCLL).
VOUT_DROOP is a linear format command. The VOUT_DROOP command must be accessed through Read Word/Write Word transactions.
VOUT_DROOP is a paged register. In order to access VOUT_DROOP for channel A, PAGE must be set to 00h. In order to access the VOUT_DROOP 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.

Bit | Field | Type | Reset | Description |
---|---|---|---|---|
15:11 | VDROOP_EXP | R | 11010b | Linear two's complement fixed exponent, –6. LSB = 0.015625 mΩ |
10:0 | VDROOP_MAN | RW | NVM | Linear two's complement mantissa. See table of acceptable values below, note that Channel A and Channel B support different acceptable values of VOUT_DROOP. |
The table below summarizes the acceptable values of VOUT_DROOP for channel A and channel B. Attempts to write any value other than those specified in the table below are treated as invalid data. The device ignores invalid data, sets the appropriate flags in STATUS_CML and STATUS_WORD and asserts the PMB_ALERT to notify the system host of an invalid transaction.
