Packaged in industry-standard DIP’s, the 3 Watt dual-output models of DATEL’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-and-

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.

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 EMI-

sensitive 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 replace-

ments 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.
