UWR-12/420-D24-C

UWR Models www.murata-ps.com Single Output, Miniature, 1" x 1", 5 Watt, DC/DC Converters OBSOLETE PRODUCT 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. DATEL’s miniature, full featured, 5 Watt UWR Models were specifically designed for today’s demanding distributed power architectures in aerospace, marine, telecom and computer applications. The converters' low cost, small size (1" x 1" x 0.45") and full 5 Watt output capability give system architects unprecedented design and layout flexibility. Occupying less than 0.5in3 total volume, these extremely compact, fully regulated and isolated (1000Vdc guaranteed) modules are available with either 5, 12 or 15 Volt outputs. Input voltage ranges are either 18-36 Volts ("D24" models) or 36-72 Volts ("D48" models).  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  5, 12, or 15V outputs  Guaranteed efficiencies to 80%  Fully regulated and isolated (1000Vdc guaranteed)  Output overvoltage protection and current limiting  –25 to +95°C operating temperature  Shielded cases (5 sides)  UL 1950, CSA 22.2 No. 234, IEC 950 Although their overall size is 50-75% smaller than many similarly rated power modules, these 1" x 1" UWR Models are exact, drop-in, pin-forpin 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 non-conductive 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 DATEL’s traditional high standards for quality and long-term reliability.  Modifications and customs for OEM's +VIN * PWM +VOUT COMMON * "D24" models only Typical topology is shown –VIN Figure 1.

Users may ground either the Common (pin 6) for normal usage or the positive side (+Output, pin 3) to effectively reverse the output polarity. Storage Temperature –55 to +125°C Filtering and Noise Reduction Flammability UL94V-0 All UWR 5 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 low-ESR, tantalum or electrolytic capacitors across the input and/or output terminals. The capacitors should be located as close to the power converters as possible. Typical values are listed below. In many applications, using values greater than those listed will yield better results.
