NJM2340
HIGH PRECISION DC/DC CONVERTER CONTROL IC
■GENERAL DESCRIPTION
The NJM2340 is a high precision DC/DC converter control
IC with a current sense amplifier. It offers a low side current
sensing which offers a DC/DC converter application with a few
external parts and minimum error. The NJM2340 has a high
input voltage and is available in small surface mount packages,
an 8-lead DMP and MSOP (TVSP). Therefore it is well-suited
for various applications.
