Murata has announced the LXDC55B step-down and LXDC44A step-up ultra-compact DC-DC converters. The LXDC55B measures 5.7x5.0x2.1mm and can support output currents up to 3.0 A. Input voltage is within the 2.7 to 5.5VDC range across the series and single output models provide the nominal output of 1.2, 1.8, 2.5, 3.0 or 3.3VDC.

Operating as an output boost converter, the LXDC44A measuring 4.0x4.0x2.0mm can deliver up to 0.7A output at 5VDC from an input of 2.7 to 4.5VDC. Constructed on a ferrite substrate with an embedded inductor, multi-layer construction and integrating the power IC and I/O capacitors together the LXDC family has good EMI suppression and reduced harmonic noise characteristics.
