Power Electronics / Power Management
The MagI3C-VDMM (Variable Step Down Micro Module) power module family from Würth Elektronik is being 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.
This product range 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, meeting the CISP-32 standard for Class B radiated interference without additional filter elements.
