Würth Elektronik eiSos has expanded its product family of MagI³C power modules with the compact MagI³C VDRM (variable step-down regulator module) in an LGA-16EP package. The module has an input voltage range of 4 to 18 V for converting voltages from the 5 V, 9 V or 12 V bus.
The very compact component (9 x 9 x 3 mm) offers scalability of currents (1 A / 2 A / 3 A) and high efficiency up to 93%. As a fully integrated DC-DC voltage converter, MagI³C VDRM contains the power stage, the regulator, the inductor, as well as input and output capacitors. Only two resistors are necessary in the external circuit to define the output voltage.
The LGA-16EP package of the MagI³C VDRM displays good thermal behaviour, and the rated current of up to 3 A can be drawn up to an ambient temperature of 85°C. The intensity of electromagnetic radiation is far below the limit stated in the EMC standard EN55022 class B. The power module is also particularly suitable for applications in industry, testing and measuring technology, medical technology and in telecoms systems.
