NJM2369
SWITCHING REGULATOR CONTROL IC FOR FLYBACK
■GENERAL DESCRIPTION
■PACKAGE OUTLINE
The NJM2369 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 power MOS-FET directly.
It is suitable for applications of flyback type switching
regulation of up to 10W.
