Würth Elektronik MagI³C-FDSM fixed step-down regulator modules

Würth Elektronik’s MagI³C-FDSM fixed step-down regulator modules now cover all bus voltages from 12 up to 48 V. The power modules facilitate development for applications with direct connection to bus voltages of 12, 24 or 48 V.

The wide input voltage range up to 74.5 V makes the module robust against voltage transients on the 48 V bus. The power modules are implemented in an SIP-3 package and provide fixed output voltages of 3.3, 5 and 12 V, with an output current up to 0.5 A.

The fully integrated DC/DC voltage converters feature fixed output voltage. Besides the power stage, the modules consist of a regulator, an inductor, and input and output capacitors.

The power modules are protected against short circuit and thermal overload. They are designed to reduce the workload involved in circuit design to a minimum, as no external components are required for operation.

For simple assembly, the family has been realised in a standard THT housing. Pre-compliance testing has shown the conducted and radiated EMI is below limits established by relevant standards.
