Protection Circuit Functional Descriptions
1. Overcurrent protection function
The overcurrent protection function detects, on a cycle-by-cycle basis, the output transistor current and turns off that
output transistor current if it exceeds 0.7A in a cycle-by-cycle manner.
2. Short circuit protection function
This IC prevents the current from increasing when the outputs are shorted by setting the switching frequency to 15kHz
if the VOS pin voltage falls below 0.8V.
Note : At startup, since the switching frequency will be 15kHz while the VOS pin voltage is 0.8V or 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.
