UWE Series www.murata-ps.com Wide Input, Isolated Eighth-Brick DC-DC Converters The UWE SeriesEighth-Bric DC-DC Converters are high-current isolated power modules designed for use in high-density system boards. Typical unit FEATURES PRODUCT OVERVIEW With dimensions of only 0.9 by 2.3 by 0.38 inches, regulation, stable no-load operation and fast load step Industry-standard through-hole eighth-brick package with 0.9 x 2.3 x 0.38 outline dimen- the UWE series open frame DC-DC converters deliver response. All units are precision assembled in a highly sions up to 75 Watts in an industry-standard eighth- automated facility with ISO-traceable manufacturing brick through-hole package. This format can plug quality standards. Choice of two wide input ranges, 9-36 Vdc or directly into quarter-brick pinouts. Several standard Isolation of 2250 Volts (Q48 models) assures 18-75 Vdc fixed-output voltages from 3.3 Vdc to 24 Vdc assure safety and fully differential (floating) operation for Fixed output from 3.3 to 24 Volts DC up to 75 compatibility in embedded equipment, CPU cards and greatest application flexibility.
