OVERVIEW
The RJW Series of high efficiency DC/DC convert-
ers are available as single and dual output versions,
3.3VDC up to 15VDC, with up to 12 Watts of output
power. The product is ideal for Telecom and
Networking applications. The converter is designed
for a 4:1 input range, either nominal 24 Volt (9VDC
-36VDC) or nominal 48VDC (18VDC-75VDC). The
converter is PCB mountable, the package has a
formfactor of 2”x1”x.04”. The standard specifica-
tions include the Pi-input filter, excellent load regula-
tion and short circuit protection. The isolation volt-
age meets the >1500VDC telecom requirements.
TYPICAL APPLICATIONS:
• 9V-36V or 18-75VDC Telecom Input
• On-Board Distributed Power
• Low Profile & Height PCB
