Original Press Release:

Würth Elektronik Expands its MagI³C-VDMM Power Module Series

More Magic Micro Modules

Waldenburg (Germany), 30 September 2019 —The MagI³C-VDMM (Variable Step Down Micro Module) power module family from Würth Elektronik is supplemented by more powerful 1 A and 1.2 A versions. The input voltage range (from 2.5 to 5.5 V) covers the standard 3.3 and 5 V bus voltages, and the adjustable output voltage ranges from 0.8 to 5.5 V. The modules have been designed for high efficiency in the low load range. Integration of the DC-DC converter and coil makes for a very compact solution in an LGA-6EP package.

The MagI³C-VDMM series is particularly suitable as a replacement for linear regulators. Applications include the supply of interfaces, microcontrollers, microprocessors, DSPs and FPGAs. Thanks to their small size and high efficiency (over 96%), they are particularly suitable for use in mobile and battery-powered devices. To save energy, the VDMM can be "put to sleep" using an additional PIN, which extends battery life.

The MagI³C VDMM series features excellent electromagnetic compatibility. The modules meet the CISP-32 standard for Class B radiated interference without additional filter elements.

The new member of the MagI³C-VDMM family is available from stock. Free samples can be requested.
