BWR-12/125-D48-C

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 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.  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 +75°C 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 "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. Input voltage ranges are either SIMPLIFIED SCHEMATIC +VOUT +VIN COMMON –VOUT –VIN PWM CONTROLLER OPTO ISOLATION REFERENCE & ERROR AMP Typical topology is shown 　 For full details go to www.murata-ps.com/rohs www.murata-ps.com/support MDC_BWR3W.D01 Page 1 of 4 BWR Series 3 Watt, Dual Output DC-DC Converters PERFORMANCE SPECIFICATIONS SUMMARY AND ORDERING GUIDE  Output ➀ ➁ ➂ ➃ Input Efficiency (mA) Min.
