SWITCHING REGULATOR CONTROL IC FOR FLYBACK
■GENERAL DESCRIPTION
The NJM2368 is a high speed switching regulator control IC
which can operate at low voltage.
It uses a totempole output circuit , so that it can drive an
external Bipolar Transistor directly.
It is suitable for applications of flyback type switching
regulation of up to 10W.
