PRODUCT OVERVIEW
Cost!
Low
Packaged in industry-standard DIP’s, the 3 Watt
dual-output models of Murata Power Solutions’
XWR Series DC-DC converters are fully regulated
(±0.5% max. line, ±1% max. load), fully isolated
(1000Vdc minimum), extremely efficient (as high
as 78% guaranteed) building blocks providing
true component-like flexibility and convenience to
designers of modern distributed power systems.

Modifi
Exploiting high-frequency (170-200kHz), flyback topologies and contemporary, highly automated, SMT
assembly techniques, BWR Model DC-DC’s have
enough room to include input (pi type) and output
filters within their package. Offering true "plugand-play" convenience, these power converters
require no external components. They operate over
the full –25 to +75°C temperature range with no
output power derating.
4.5-9V ("D5" models), 9-18V ("D12" models) or
an ultra-wide 18-72V ("D48" models). Transient
response time is a quick 200μsec.
These extremely rugged modules are fully encapsulated with a thermally conductive potting compound. They are moisture and vibration resistant
and have established a reputation for outstanding
MTBF. For telecommunication, computer and other
EMI-sensitive applications, these DIP-packaged
DC-DC converters offer full EMI/EMC characterization data.
Industry-standard pinouts make Murata Power
Solutions’ BWR Model 3W DC-DC’s ideal replacements for other more costly, less reliable power
converters. Similarly, they are excellent choices for
new design-ins in systems demanding small size,
low cost and high reliability.
Output voltages are either ±5, ±12 or ±15 Volts.
