■PIN CONFIGURATION
The NJM2374A is a PWM DC/DC converter IC.
It features fixed frequency type PWM control for better noise
handling and to avoid intermittent oscillation observed in a
simplified controller.
It is suitable for Step-Up, Step-Down and Inverting applications
for EMI sensitive application.
