*Complement explanation
Here shows the general usage of the modes 1 to 3 as follows.
MODE 1 is set by connecting the ADJ(+) and ADJ(-) terminals with VSS. In the MODE1 state, by cutting the
bonding wire connected with ADJ(+) or ADJ(-), the IC enters the MODE2 or MODE3, respectively. The current in
MODE1 can be corrected by about –6 % or +6 % in MODE2 or MODE3, respectively.
