8) Note on the Use of Output Reference Voltage
When output reference voltage adjustment is used, please be aware of the following.
When ELV[8] is changed from 0h to 1h, VOUT output voltage may shift by offset of an internal circuit (around 1
code of ELV[7:0] as maximum). When adjusted using ELV[8] = 1h, please check VOUT output voltage by
ELV[7:0] = 00h, and as the start point adjust to the target output reference voltage.
9) Note on the Use of Offset Voltage Fine Adjustment
When offset voltage fine adjustment is used, please be aware of the following. (It becomes the same contents as
the preceding paragraph.)
When EOCF[7] is changed from 0h to 1h, VOUT output voltage may shift by offset of an internal circuit (around
1 code of EOCF[6:0] as maximum). When adjusted using EOCF[7] = 1h, please check VOUT output voltage by
EOCF[6:0] = 00h, and as the start point adjust to the target offset voltage.
