Wurth Elektronik Introduces 0.3 A Variable Step-Down DC-DC Converter

Wurth Elektronik, a leading manufacturer of electronic components, printed circuit boards and intelligent power and control systems, has unveiled the VDMM 171936001 MagI³C power module. This newly launched module provides a fully integrated DC-DC converter including the switching regulator with integrated MOSFETs, compensation, and shielded inductor in one package.

The 171936001 offers high efficiency and delivers up to 0.3 A of output current. It operates with an input voltage from 3.5 V to 60 V. This power module is tailor-suited for space-constrained applications that need a high power density. The selectable forced PWM or PFM/PWM mode allows for optimizing light load efficiency and output voltage ripple. The 171936001 is available in an LGA-12 package (8 x 5.5 x 2.3 mm). This module has integrated protection circuitry that guards against thermal overstress with thermal shutdown. It protects against electrical damage using overvoltage, overcurrent, short-circuit, and undervoltage protections.
