The N Series are high quality,
wide-input, efficient 15 and 40
watt DC/DC converters. Features
include: Pi input filtering to reduce input
reflected ripple, and efficiencies to
85%. Other key features include:
overvoltage protection, output trim
adjustability (±10%), and continuous
short circuit protection. Packaged in a
six-sided shielded case, the 15 watt N
Series measures only 2.0” x 2.0” x 0.4”.
Packaged in a six-sided shielded case,
the 40 watt N Series measures only
2.5” x 3.5” x 0.83”.
Applications
The N Series is designed for battery-
powered or portable, space-critical
applications, as well as other applica-
tions not requiring input-output isola-
tion.
