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

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.

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.
