NJM2340
HIGH PRECISION DC/DC CONVERTER CONTROL IC
■GENERAL DESCRIPTION
NJM2340 is a high precision DC/DC converter control IC
with current sense amplifier.
It uses a low side current sensing which reduces external
components and improves accuracy.
It is applicable for a wide range of application since it
features high operating voltage and small outline packages.
