Würth Elektronik MagI³C FDSM power modules

Würth Elektronik’s MagI³C FDSM power modules with fixed 3.3 or 5 V output voltages are now available with an input voltage of 36 V, following on from versions with maximum input voltages of 28 and 42 V. The components in a SIP-3 package can be used to meet the requirements for the transient capability of a 24 V industrial voltage network. The modules operate from 6 to 36 V VIN and generate a fixed output voltage of 3.3 or 5 V at a current of up to 1 A.

The power modules are fully integrated DC/DC voltage converters with fixed output voltage. The modules comprise the power stage, controller, inductors, and effective operational input and output capacitors. They also come with thermal overload and short circuit protection.

No external components are required for operation. The workload of circuit design is thus reduced to a minimum, allowing applications to be brought to market quickly. The standard THT housing for easy mounting is pin-compatible with the L78x linear controllers. The radiated and line-bound interference of the modules is below the limit set by the EMC standard EN55032/CISPR32 Class B.
