The VOUT_MAX command sets the maximum output voltage. The purpose is to protect the devices on the output rail supplied by this device from a higher than acceptable output voltage. VOUT_MAX imposes an upper bound to any attempt to program the output voltage to a VOUT_EQUIV setting by changing any of the following registers:
The exponent is set be VOUT_MODE at –9 (equivalent of 1.953 mV/count). Use Equation 6 to calculate the programmed output voltage.
The range of valid VOUT_MAX values is dependent upon the configured (29h) VOUT_SCALE_LOOP as shown in Equation 7.
If, while the output voltage is turned on, any attempt is made to program: (1) VOUT_EQUIV to be greater than VOUT_MAX; (2) VOUT_MAX to be less than, or equal to, VOUT_MIN, or; (3) VOUT_MIN to be greater than, or equal to, VOUT_MAX – the device will:
For loop slave device, this command cannot be accessed. Any writes to this command will be ignored. An attempt to read or write this command will result in a NACK’d command, the reporting of an IVC fault, and triggering of SMB_ALERT.
