Power module series expanded with variable step-down module

With MagI³C-VDLM, Würth Elektronik presents three power modules in the LGA-12EP package for the 24V industrial power bus. The modules are characterised by high resilience to voltage transients on the 24V bus and an extremely wide input-voltage range from 3.5V to 38V. The module, measuring just 10mm × 6mm × 3.1mm, is available with an output current of 1A, 2A, or 3A.

The series of power modules provides a fully integrated DC-DC power supply that combines all essential components in a compact package: switching regulator with integrated MOSFETs, controller, compensation circuitry, and a shielded inductor. The power module maintains a constant, selectable PWM switching frequency across the operating range, thereby optimising output ripple for sensitive and precise applications. It achieves peak efficiency of up to 94%.

The MagI³C-VDLM power modules are developed for use in point-of-load DC-DC applications on 24V, 12V, and 5V buses. Typical applications include test and measurement technology, medical technology, industrial electronics, and telecommunications. The module is ideal for supplying interfaces, MCUs, MPUs, DSPs, and FPGAs. It offers excellent EMC behaviour and complies with the EN55032 Class B / CISPR-32 standard.
