Würth Elektronik adds 74.5V to its MagI³C-FDSM family
2 May 2022 
The fixed step-down MagI³C-FDSM regulator modules now cover all bus voltages from 12 to 48V. For applications with direct connection to bus voltages of 12, 24 or 48V, the FDSM module has a wide input voltage range up to 74.5V, to be robust against voltage transients on the 48V bus. The modules are implemented in an SIP-3 package and provide fixed output voltages of 3.3, 5.0 and 12V with an output current up to 0.5A.
The modules are fully integrated DC/DC voltage converters with fixed output voltage and consist of a regulator, inductor as well as input and output capacitors. The power modules are protected against short circuit and thermal overload. The module eliminates the need for external components in circuit design. They are supplies in a standard through hole technology housing.
Pre-compliance testing of the evaluation board has shown the conducted and radiated EMI is below limits established by relevant standards, reports the company.
All MagI³C-FDSM power module versions are available from stock. Free samples can be requested.
