... Make sure to leave adequate margin for this IC variation. ９． On operating Slow Start Control (SS is less than 2.2V), It does not operate Timer Latch. １０． By STB voltage, BD9885FV is changed to 2 states. Therefore, do not input STB pin voltage between one state and the other state (0.5～1.4V). ...
