Murata adds to its growing line up of ultra compact DC-DC converters

Murata has announced additions to its LXDC series of ultra compact DC-DC converters. The new devices comprise the LXDC55F and LXDC55K step down converters. Both models offer a voltage trim function that allows adjustment of the output voltage within the range of 0.8 to 5.3 VDC for the 55F and up to 3.6 VDC for the 55K converter.

The LXDC55FAAA-203 measures 5.0 x 5.7 x 2.1mm and can support an input voltage in the range of 4.0 to 14.0 VDC. Maximum output current is up to 1.5 A.

Capable of supporting an output current up to 3 A the LXDC55KAAA-205 measures 5.0 x 5.7 x 2.1mm. Input voltage is within the range of 2.7 to 5.5 VDC.

The converters are constructed on a multilayer ferrite substrate that integrates an embedded inductor and the power IC. Using this approach the LXDC family exhibits good EMI suppression and reduced harmonic noise characteristics.

These highly efficient converters use a synchronous rectifier technology and are suitable for applications that require an extremely small DC-DC conversion footprint where a discrete approach is not possible due to space limitations. The LXDC series are aimed not only at consumer electronic devices such as cellular phones, tablets, games consoles, digital cameras but also at communication applications such as base stations.
