PRODUCT OVERVIEW
Packaged in industry-standard DIPâs, the 3 Watt
dual-output models of DATELâs XWR Series DC/DC
converters are fully regulated (±0.5% max. line,
±1% max. load), fully isolated (1000Vdc minimum),
extremely efï¬cient (as high as 78% guaranteed)
building blocks providing true component-like
ï¬exibility and convenience to designers of modern
distributed power systems.
Exploiting high-frequency (170-200kHz), ï¬yback
topologies and contemporary,
highly automated, SMT assembly techniques, BWR
Model DC/DCâs have enough room to include input
(pi type) and output ï¬lters within their package.
Offering true "plug-and-play" convenience, these
power converters require no external components.
They operate over the full â25 to +75°C tempera-
ture range with no output power derating.
Output voltages are either ±5, ±12 or ±15 Volts.
Input voltage ranges are either
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 encap-
sulated with a thermally conductive potting com-
pound. 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 characteriza-
tion data.
Industry-standard pinouts make DATELâs BWR
Model 3W DC/DCâs ideal replacements for other
more costly, less reliable power converters. Simi-
larly, they are excellent choices for new design-ins
in systems demanding small size, low cost and
high reliability.
