SWITCHING REGULATOR CONTROL IC FOR FLYBACK

WITH CURRENT SENSE AMPLIFIER

■GENERAL DESCRIPTION

■PACKAGE OUTLINE

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.
