DESCRIPTION
The PWR72 is a 3W, single-channel, dual-output DC/DC
converter designed for low cost spot power conversion and
ground elimination applications.
It provides a plus and minus output voltage approximately
equal to the input voltage magnitude. The PWR72 operates
over a wide range of input voltages from 5V
DC
to 22V
DC
. Its
unregulated outputs give the PWR72 high efficiency power
conversion.
Surface-mounted devices and manufacturing processes are
used in the PWR72 to give the user a device which is more
environmentally rugged than most DC/DC converters. The use
of surface-mounted technologies also gives the PWR72 supe-
rior isolation voltage. A third advantage of using surface-
mounted technologies is low manufacturing cost.

NOTES: All dimensions are in inches
(millimeters).
GRID: 0.100 inches (2.54 millimeters)
Marked with: specific model ordered, date
code, job code.
MATERIAL: Units are encapsulated in
a low thermal resistance molding
compound which has excellent
chemical resistance, wide operating
temperature range, and good electrical
properties under high humidity
environments. Lead material is brass
with a solder plated surface to allow
ease of solderability.
