Micro DC-DC Converter (LXDC Series) | Murata

NEW 10.2.13
Micro DC-DC converter series has now been expanded to include the 55F and 55K additions to the product line that deliver ultra-compact size and superior EMI noise suppression.

By combining a number of Murata's proprietary materials and technical capabilities (specifically ferrite material expertise, multilayer processing, and power module design), Murata developed a product line that delivers ultra-compact size and EMI noise suppression. Moreover, the LXDC2UR and LXDC3EP series are the world's smallest DC-DC converters (at 600mA and 1A current ratings, respectively) that also incorporate the I/O capacitors into the same package. Murata also provides the LXDC55B series, available at 3A.

A key feature of the LXDC line is the embedding of the power inductor within the actual ferrite substrate. By utilizing this structure, the IC can be mounted directly above the power inductor coil with almost no pattern length to diminish leakage radiation noise. The I/O connections are also routed through this same ferrite substrate to create a function similar to ferrite beads that significantly reduces conductive noise. Lastly, board space is greatly decreased when using this product versus other discrete surface mount designs.
