CLM:
Input terminal for detection of the pulse-by-pulse
overcurrent protection.
Normally, it is recommended that a filter be at-
tached externally.
GND:
Grounding terminal
V
Output terminal for directly driving the power
MOSFET.
It uses the totem pole type output.
The maximum rating of the output current :

Terminal for applying power supply voltage.
It monitors the supply voltage and has the opera-
tion threshold of start/stop/OVP reset.
