Murata Americas - uDCDC

uDCDC Murata Electronics new micro DC-DC converter series utilizes a unique ferrite substrate to embed the power inductor. 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. The LXDC2UR and LXDC3EP series are believed to be the world's smallest DC-DC converters (at 600mA and 1A current ratings, respectively) that also incorporate the I/O capacitors onto the same package.

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 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.

Product Features:
  • Low EMI noise and small footprint due to inductor-embedded ferrite substrate
  • High efficiency using synchronous rectifier technology and PFM/PWM auto-select
    function (forced mode available on some models)
  • Input voltage range = 2.3 ~ 5.5V & 14V (55F series)
  • See individual specifications for Output Voltage and Load Current
  • Switching frequency = 2.5, 2.8, 3.0, 3.3, 4.0, or 6MHz
  • Operating temperature range = -40 to +85°C
