Micro DC-DCs feature Embedded Power Inductor and Ferrite Substrates

October 08, 2013 by Jeff Shepard

Murata Americas today announced the expansion of its LXDC line, a micro dc-dc converter series that utilizes a unique ferrite substrate to embed the power inductor. The company combined a number of its proprietary materials and technical capabilities (specifically ferrite material expertise, multilayer processing, and power module design) to develop the 55F and 55K additions to the product line that deliver ultra-compact size and superior EMI noise suppression. The micro dc-dc converter is suited for applications that require a miniaturized footprint. Target uses include cellular phones, personal digital assistants (PDAs), mobile internet devices, digital cameras, eBooks, tablets, wireless LAN, Bluetoothâ„¢, portable game consoles, music players, base station, and 12V ac-dc adaptors.

A key feature of this embedded structure is that the IC can be mounted directly above the power inductor coil with almost no pattern length to diminish leakage radiation noise. The new LXDC55KAAA-205 (5.7 x 5.0 x 2.1mm) allows for more versatility in distributed power architectures. In addition to better EMI noise suppression and a smaller size, it also provides an adjustable output voltage between 0.8 and 3.6 volts. Further, up to 3A can be delivered with input voltages ranging from 2.7-5.5V.

“Design engineers are under constant pressure to develop smaller and smaller end products. Murata’s LXDC series enables them to achieve just that,” said Geoff Brock, Marketing Manager, New Products Murata Americas. “By using Murata’s proprietary inductor-embedded ferrite substrate and multilayer processing technologies, we deliver the class-leading products that feature-rich products require.” Samples of the LXDC series samples are available for $3.00 (in quantity) with an approximate lead time of 14 weeks.
