The first 4 bits (MSB-bits) of the data field are used to select the output voltage where the second 4
bits (LSB-bits) of the data field are used to trim the output voltage (percent of output voltage). The
default value for the data field is as follows.
Table 9:
On power up, the output voltage is set according to R
be field programmed by setting bit 3 and bit 7 to “1”. The output voltage and percent set are selected
according to
Table 10: Voltage and Percentage Set
All combinations of the VSET
provide maximum flexibility in output voltage selection
To select the output voltage, use the value from
Table 11: Output Voltage Selection
