UWE Series www.murata-ps.com Wide Input, Isolated Eighth-Brick DC-DC Converters The UWE SeriesEighth-Bric DC-DC Converters are high-current isolaT ted power modules designed for use in high-density system boards. Typical unit FEAFEATURESTURES PRODUCT OVERVIEW With dimensions of only 0.9 by 2.3 by 0.38 tight line/load regulation, stable no-load operation Industry-standard through-hole eighth-brick package with 0.9 x 2.3 x 0.38 outline inches, the UWE series open frame DC-DC convert- and fast load step response. All units are precision dimensions ers deliver up to 75 Watts in an industry-standard assembled in a highly automated facility with ISO- eighth-brick through-hole package. This format traceable manufacturing quality standards. Choice of two wide input ranges, 9-36 Vdc or can plug directly into quarter-brick pinouts.

I/O caps are necessary for our test equipment and may not be needed for your application. All speci cations are at nominal line voltage, nominal output voltage and full load, +25 C. Load regulation range: 0.1-3A. This is required only for our test equipment. The converter will unless otherwise noted. See detailed speci cations. operate at zero output current with degraded regulation. Output capacitors are 1 F ceramic in parallel with 10 F electrolytic. Input cap is 100 F. All caps are low ESR types. Contact Murata Power Solutions for details.
