Applications
* with height limitation such as HDD or space-
saving applications. Current limit value can be chosen either 1.2A (MIN. ) when the LIM pin is high level, or 0.6A (MIN. ) when the LIM pin is low level
for using the power supply which current limit value differs such as USB or AC adapter. With the MODE
