BWR Series www.murata-ps.com 3 Watt, Dual Output DC/DC Converters Typical units FEATURES PRODUCT OVERVIEW Low Cost! 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. Automated, SMT-on-pcb construction No external components required 5, 12 or 15 Volt outputs Choice of 3 input voltage ranges: 4.5-9 Volts 9-18 Volts 18-72 Volts 1.25" x 0.8" x 0.45" DIP form factor Industry-standard package and pinout Fully isolated, 1000Vdc guaranteed Guaranteed efficiencies to 78% -25 to +75C operation with no derating UL 1950, CSA 22.2 No. 234 and IEC 950 EMI/EMC characterized Modifications and customs for OEM's 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 +75C 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 200sec. 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 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.

Operation under no-load conditions will not damage these devices; however they may not meet all listed specifications. Application-specific internal input/output filtering can be recommended and perhaps added internally upon request. Contact DATEL Applications Engineering for details. Devices can be screened or modified for higher guaranteed isolation voltages. Contact DATEL Applications Engineering for details. Devices can be warranted or screened for lower-temperature operation. Contact DATEL Applications Engineering for details. See DATEL's new BST 3W Models for guaranteed operation to -40C. Since these are isolated DC/DC converters, their outputs are "floating." Any BWR model may be configured to produce an output of 10V, 24V or 30V (for 5V, 12V or 15V models, respectively) by applying the load across the +Output and -Output pins (pins 6 and 8), with either output grounded. The Common (pins 5 and 7) should be left open. Minimum 20% loading is recommended under these conditions. Filtering and Noise Reduction All BWR 3 Watt DC/DC Converters achieve their rated ripple and noise specifications without the use of external input/output capacitors. In critical applications, input/output ripple and noise may be further reduced by installing electrolytic capacitors across the input terminals and/or low-ESR tantalum or electrolytic capacitors across the output terminals. Output capacitors should be connected between their respective output pin (pin 6 or 8) and Common (pins 5 and 7) as shown in Figure 2. The caps should be located as close to the power converters as possible. Typical values are listed in the tables below. In many applications, using values greater than those listed will yield better results.
