Note: The absolute maximum ratings of a semiconductor device are a set of ratings that must not be exceeded, even for a
moment. Do not exceed any of these ratings. Exceeding the rating (s) may cause the device breakdown, damage or
deterioration, and may result injury by explosion or combustion. Please use the IC within the specified operating ranges.
Note 1: VMI, VSP, VSOFT, VOFF, and LA pins
Note 2: OUT1, OUT2, FG and RDO pins
Note 3: Power dissipation must not be exceed
Note 4: Mounted on a glass epoxy board
