PRODUCTION DATA
The device has four different output voltage ranges. The VRANGE[1:0] bits in the CONTROL2 register control which range is active (see Table 7-3). The default output voltage range is determined by the VSETx pins.
VRANGE[1:0] | Voltage Range |
---|---|
0b00 | 0.4 V to 0.71875 V in 1.25-mV steps |
0b01 | 0.4 V to 1.0375 V in 2.5-mV steps |
0b10 | 0.4 V to 1.675 V in 5-mV steps |
0b11 | 0.8 V to 3.35 V in 10-mV steps |
Every change to the VRANGE[1:0] bits must be followed by a write to the VSET register – even if the value of the VSET[7:0] bits does not change. This sequence is necessary for the device to start to use the new voltage range.
When switching to or from the 0.8-V to 3.35-V range, the device switches the internal reference between 0.4 V and 0.8 V. To avoid any output voltage over or undershoot that can occur during the change, the VRANGE change must be done at an output voltage that occurs in both the new range and old range and the VSET[7:0] bits must set the same output voltage in both the new range and old range.
