Caution 1) Absolute maximum ratings represent the value which cannot be exceeded for any length of time.
Caution 2) Even when the device is used within the range of absolute maximum ratings, as a result of continuous usage under high temperature, high current,
high voltage, or drastic temperature change, the reliability of the IC may be degraded. Please contact us for the further details.
Stresses exceeding Maximum Ratings may damage the device. Maximum Ratings are stress ratings only. Functional operation above the Recommended Operating
Conditions is not implied. Extended exposure to stresses above the Recommended Operating Conditions may affect device reliability.

Protection Circuit Functional Descriptions
Overcurrent protection function
The overcurrent protection function detects, on a pulse-by-pulse basis, the output transistor current and turns off that
output transistor current if it exceeds 0.7A in a pulse-by-pulse manner.
Limit current
Inductor current
SWOUT voltage
Short circuit protection function
This IC prevents the current from increasing when the outputs are shorted by setting the switching frequency to
30kHz if the VOS pin voltage falls below 0.8V.
Note : At startup, since the switching frequency will be 30kHz while the VOS pin voltage is 0.8Vor lower, the
current capacity is reduced. If the load is applied at startup and the applications has trouble starting, increase
the value of the inductor to resolve this problem.
