BWR-5/500-D24-C

BWR Models www.murata-ps.com Miniature 5 Watt DC-DC Converters Typical units FEATURES PRODUCT OVERVIEW  Small size, 1" x 1" x 0.45" The migration to distributed power is accelerating. The critical need for accurate voltages, tight regulation and rapid transient response is propelling the move to power processing at the "point-ofuse" with low-power DC-DC converters physically located right at their loads.  Full 5 Watts output power  No external components required  Drop-in replacements for many standard, 2" x 1" DC-DCs  Wide input voltage ranges: 18-36V or 36-72V  Standard output voltages: ±5, ±12, ±15 Volts  Guaranteed efficiencies to 80% MPS’s miniature, full featured, 5 Watt BWR Models were specifically designed for today’s demanding distributed power architectures in aerospace, marine, telecom and computer applications. The converters’ small size (1" x 1" x 0.45"), full 5 Watt output capability and low cost give system architects unprecedented design and layout flexibility.  Fully regulated and isolated (1000Vdc guaranteed)  Output overvoltage protection and current limiting  –25 to +95oC operating temperature Occupying less than 0.5in3 total volume, these extremely compact, fully regulated and isolated (1000Vdc) modules are available with ±5, ±12 or ±15 Volt outputs. Input voltage ranges are either 18-36 Volts ("D24" models) or 36-72 Volts ("D48" models).  Shielded cases (5 sides)  UL1950, CSA 22.2 No. 234, and IEC950  Modifications and customs for OEMs +VIN (1) Although their overall size is 50-75% smaller than many similarly rated power modules, these 1" x 1" BWR Models are exact, drop-in, pin-for-pin replacements for many standard 2" x 1" and 2" x 2", 5 Watt modules. They achieve their small size and low cost by exploiting a novel feedback approach that does not depend upon traditional optocoupler techniques. All models are 5-side shielded and have a nonconductive baseplate that permits pc-card runs to be placed beneath the package. Units are assembled using high-speed automated SMT techniques and are fully encapsulated with thermally conductive potting compound. Every unit is electrically tested before and after encapsulation, 100% burned-in under full load, hi-pot tested, and final-electrical tested prior to shipment. Every unit meets MPS’s traditional high standards for quality and long-term reliability. * +VOUT (3) PWM COMMON (4) –VOUT (6) –VIN (2) 　 * "D24" models only For full details go to www.murata-ps.com/rohs Figure 1.
