For circuit currents, ' ' denotes current flowing into the IC, and ' ' denotes current flowing out of the IC.
* 1: Except for the operating ambient temperature and storage temperature, all ratings are for T
* 2: The voltage in the step-up voltage circuit exceeds the supply voltage.
* 3: The power dissipation shown is the value of independent IC without a heat sink at T
* 4: o
* 5: m
* 6: n
* 7: n
For the allowable value of the step-up voltage, refer to " Electrical Characteristics".
of the " Application Notes" for details.
