PRODUCT OVERVIEW
The NDX series of DC/DC converters provide up to
7.5W of output power with single or dual outputs.
Unbalanced loading capability with an optional
input control pin. Input voltages of 5V (4.5V to 9V),
12V (9V to 18V), 24V (18V to 36V), and 48V (36V
to 75V) with outputs of 5V, 12V or 15V provided.
The device is housed in a 5 sided metal case
potted with UL 94V-0 rated material. The pinout is
an industry standard 5 pin arrangement with an
additional optional control pin.
