SWITCHING REGULATOR CONTROL IC FOR FLYBACK
WITH CURRENT SENSE AMPLIFIER
IGENERAL DESCRIPTION
The NJM2381 is a low voltage operation DC/DC converter
control IC.
It features totem pole output directly driving external
bipolar transistor and operates at high switching frequency
which improves transient response.
It is suitable for LCD back light, and other portable
applications.
