PIN CONFIGURATION
The NJM2382 is a low voltage operation switching regulator
control IC.
It features totem pole output directly driving external bipolar
transistor and operates at high switching frequency which
improves transient response. In addition, low power standby
function is incorporated.
It is suitable for LCD back light, and other portable
applications.
