Packaged in industry-standard DIP’s, the 3 Watt dual-output models of DA TEL’ s 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.
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 "plug-andplay" convenience, these power converters require no external components. They
operate over the full –25 to +75°C temperature 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 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 EMIsensitive applications, these DIP-packaged DC/DC converters offer full EMI/EMC
characterization data.
Industry-standard pinouts make DATEL ’s 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.
