Würth Elektronik Expands MagI³C with Variable Step-Down Modules

30.7.2025
Reading Time: 3 mins read
A A

Würth Elektronik expands its MagI³C power module series with variable step-down modules featuring high current outputs.

Würth Elektronik has expanded its successful MagI³C-VDLM power module series with two new models. With output currents of 4 A and 5 A respectively, they further enhance the performance of the existing portfolio of compact DC/DC power supply modules.

The new modules are designed for input voltages from 4 to 36 V and come in a space-saving LGA-26 package (11 × 6 × 3 mm).

They provide an output voltage from 1 to 6 V and, like all power modules in the MagI3C-VDLM series, integrate the essential components for a DC/DC power supply in a compact package: switching regulator with integrated MOSFETs, controller, compensation circuitry, and a shielded inductor.

The power modules maintain high efficiency across the entire output current range by automatically switching between operating modes based on load requirements. So they ensure minimal output ripple – ideal for precise and interference-sensitive applications. Typical applications include point-of-load DC/DC converters, industrial, medical, test and measurement equipment, or for supplying power to DSPs, FPGAs, MCUs, MPUs, and interfaces.

Excellent efficiency

The MagI3C-VDLM modules achieve peak efficiencies of up to 96 percent and impress with their excellent EMC performance in accordance with EN55032 Class B / CISPR-32. Additional features include selectable switching frequencies, automatic PFM/PWM transition, and a sync function for synchronizing to individual clock frequencies.

The new MagI³C-VDLM modules are now available from stock without a minimum order quantity. All customers are offered design and layout reviews as well as EMI filter design support as a service.

Characteristics

  • Low conducted and radiated EMI (compliant to EN55022 class B / CISPR-22)

LGA-12EP

  • For direct connection to 24 V industrial voltage network
  • Low profile LGA-package
  • Ideal for space constrained applications
  • 2 solder cycles supported

LGA-16EP

  • Low profile LGA-package
  • Stand alone solution (CIN and COUT integrated, 2 external components to set VOUT)
  • Ideal for space constrained applications
  • 2 solder cycles supported

LGA-26

  • For direct connection to 24 V industrial voltage network
  • Sync function for custom switching frequencies
  • Low profile LGA-package
  • Ideal for space constrained applications
  • 2 solder cycles supported

Applications

  • Point-of-Load DC-DC applications from 18V, 15V, 12V, 9V, 5V industrial rails
  • Test and measurement equipment
  • Medical equipment
  • Interface supply
  • Supply of microcontrollers, microprocessors, DSPs, FPGAs
  • Industrial electronics
  • Telecommunications
