Note 1: Due to operation of the temperature derating function, measure when Ta
= 25°C.
Note that fluctuation in R_sens resistors is not included in the specified value.
Io may be different from the specified value due to the relation between the inductor value and load.
Note 2: This rating is guaranteed by the design.
